    Credibility Is the Barrier to Entry in Silicon

    Darian Domocos told me the hardest part of starting a CPU company wasn’t the engineering; it was getting anyone to believe that two young guys from Romania could do it. He’s the CEO and co-founder of Fiora5, a startup that develops and licenses RISC-V processor IP out of Europe. That’s where the conversation started before it charged through supply chain politics, why he’s ignoring the datacenter on his path to market, and what he’s reading to keep growing. Our discussion hit a pretty wide range of topics, from career advice to nation state security. My three favorite themes from the discussion were: Winning with RISC-V We discussed open source instruction sets and how you build a business model around one. Closed systems still have the edge, but given how rapidly the EDA world is changing, and how rapidly the architecture of chips is changing, open source is having a moment. As we discussed with Daniel Schulz in Episode 8 of The Siliconimist, many parts of the silicon model are moving rapidly toward open: as more of the industry builds on it and embraces it, a self-reinforcing cycle starts. Arm’s advantage is ecosystem maturity, not the instruction set. Toolchain, debugging, integration, forty years of programmer habit. As Darian put it: “you might have a really amazing RISC-V core, but because you don’t have the auxiliary software it is harder to integrate.” The unlock is standardization, specifically RVA23, which he called out as the single biggest step RISC-V International has taken. Sovereignty Through Supply Chain Driving RISC-V further and faster are the shifts in the global supply chain and the changing geopolitical winds. Open source can mean sovereignty. With no single controlling company, nations have fewer effective pressure points to control or compromise the instruction set. With America and China locked in on each other, the EU has decided that they too need more sovereignty over their chips. Rather than cast their lot with one or the other, they’re trying to build a local ecosystem. Europe won’t replace the entire supply chain, or control it, and unlike China they’re being realistic about that. Rather, if they control critical pieces of the chain, they buy optionality for the future. The strategy’s not MAD, it’s not self reliance, and it’s not Lenin’s “commanding heights of the economy” worldview. Both the US and China are closer to those approaches of strategic supply chain security. It’s more like Global Value Chain integration: specialize and participate in order to gain security and be irreplaceable (also, good career advice!). Fiora5 is capitalizing on this as the EU invests in startups to support various parts of the semiconductor industry. Agency as Compensation Given the hot market for talent, how does an upstart like Fiora5 attract the people they need to win? With pay packages climbing, it’s more expensive than ever to get high-end talent. You can’t compete on salary alone, so Fiora5 gives founding engineers stock options, giving agency plus equity. Giving people more responsibility and more control attracts and motivates them. If you’re a young, talented engineer, you too might prefer a role at a startup that doesn’t have the resources to micromanage you. And early career growth can have big payoffs in the long run . . . the long game wins. What he’s reading I end every episode the same way: “what are you reading, and what’s your favorite resource for learning?” Darian is working through The Confidence Game by Maria Konnikova, a book about con artists and why people believe them. He got there through an early interest in social engineering, and he thinks it’s useful for a founder: understand what actually motivates the people across the table. Coming full circle, that brings it back around to the start of the conversation. He started by telling me his biggest problem was credibility, that nobody wanted to bet on two unknown engineers from Romania. Founding a company is a confidence game in the honest sense of the phrase: you have to get people to believe in something before it’s true, and then go make it true. For the technical side, he pointed at Onur Mutlu’s computer architecture lectures from ETH Zürich, free on YouTube, which he called his holy grail of learning. He also reads Dylan Patel , SEMIVISION , Mario Gabriele, EE Times, and Tom’s Hardware. Darian will be in the US in late September for the RISC-V Summit, and Fiora5 is raising a larger round in Q1.

    The Open Source Silicon Business Model

    The business of semiconductor design is pure intellectual property: the worlds most creative minds, building ideas that generate trillions of dollars of value. Without the minds and the ideas, the entire industry is worth almost nothing. If this business can’t own their IP there is no business. So why would anyone build a business that gave it all away? aesc’s Business Model I sat down with Daniel Schultz, founder of aesc silicon, who’s pioneering a new semiconductor business model based on open source principles. Daniel is bootstrapping his startup. The model is not entirely new: his approach mirrors Linux’s (Red Hat) success. The core IP is free (for others), but the idea is that the value comes from support, customization, and specialized services. Revenue comes less from the product, more in the support. Tim told us this (sorta), when we were discussing wafer.space’s success: similar to Linux, lots of users means lots of demand for improvement, and that ends up driving design and improvement faster than any traditional IP model could. If the success of linux is any indication, this could work. Who Buys Open Source? It’s early days for Daniel and the open-source silicon movement. But a customer is important for a business to survive . . . so who’s buying? Daniel points to verifiable security as the killer app: silicon that, because it’s open source through the entire design and manufacturing supply chain, it can be verified back-door free. Chips that have auditability (you can verify nothing was slipped into your design before it hit the fab) will have an edge in cryptographic engines must be open to be trusted. A growing source of potential customers is the increasing demand for custom chips from smaller companies. As more companies come up with more specialized chips, this has driven a benevolent cycle for fabless companies. Open source IP could drive that faster, with less time and money locked up in IP licensing. Daniel's bet is that falling tool costs (no Cadence/Synopsys seat) plus open IP lower the barrier so far that lots of small companies start making custom chips, and that's the demand wave. The Raspberry Pi example (one engineer made their own microcontroller) is the concrete proof point. IP Forge We got a sneak preview into some open source software Daniel’s building to support this vision, IP Forge. I actually found it snooping around the aesc github account before our interview. The concept is a package manager for open-source IP blocks. Similar to NPM or python packages (shout out to uv, my favorite python package manager!) a designer could source, compare, and download blocks of code right into their project. I like this: IP Forge seems like a crucial tool to get customers locked in to an environment like python’s pip or uv package managers, where development speed is accelerated by rapidly building on other’s building blocks. Experimentation Gets Cheap Daniel touched on one of the super powers of open-source and the tools that are growing up around it: the cheapness of experimentation. This could be the near-term factor that drives growth in the open-silicon space. The $4-7k Wafer.Space runs let companies "try and error" instead of betting the R&D budget. We see that in Tim’s experiments, and in the Tiny-Tapeout runs: the price is low enough, engineers can take some true risks. Daniel points this out to me: there are open-source FPGAs being taped out, RISC-V processors going on wafer.space, and BlenderGDS is making chip renders that double as marketing only because the designs are open. Inexpensive experimentation harnesses the power of biological evolution: change the design, experiment, try and die. Open source software further lowers the price. The founder's wager. The best part of the interview for me was talking to Daniel about why he chose to walk off on his own. He’s taking a very long view of the ecosystem, avoiding VC by choice, bootstrapped, a real legal entity, and he candidly says that "it's probably not the time to make a lot of money now, but open source will be a thing and it's fun." I admire the long-range vision Daniel has for the ecosystem, and his courage for making a bet on himself and his vision.

    Semiconductors: Made in America

    I gave this talk to a group at the American Corner in Almaty in April, 2026, in Almaty Kazakhstan. I was invited to come talk about America, it’s the 250th birthday of America. I’m an American living in Almaty Kazakhstan. We are rare. So I took the opportunity to talk about two of my favorit things: America, and semiconductors. It’s an interesting subject, and semiconductor history ties into American culture. I like history, I’m an engineer, and I like stories . . . it’s rare I get to tie those three things together. An American in Almaty Being an American here feels like being a celebrity. The people, who are by far the kindest and most polite people (rivaling Omani’s who are also incredibly generous and polite), they’re genuinely curious about you and what you think of Kazakhstan. It’s not hard to find nice things to say about the place. The lingua-franca of this region is Russian (Kazakhstan was colonized by Russia, once by the Tsars and once by the Soviets), and living here requires you to know just a bit of it. When I stepped off the plane two years ago, I did not understand a word of Russian or Kazakh, and even worse, I couldn’t read the alphabet (street signs and names can still be challenging). Kazakhs always forgive you if you don’t speak Kazakh or Russian; if they speak English, even a few phrases, they’re game to try and talk to you. One of the most endearing things here is when you meet someone realizes you’re an American, they don’t speak English, and they grab their eldest child, and proudly tell them to speak English to you. Brave little kids come up to me all the time, at the airport, on the street, at a restaurant . . . they come right up and speak English to you. I meet so many Kazakhs that have lived and worked in the US, they always have kind things to say about my people. So this recording was my talk, at the American Spaces, about the history of semiconductors and why they were invented in America. Semiconductors in America Semiconductors go all the way back to Edison; he discovered the photoelectric effect (“Edison effect” . . . a foundational idea behind solid state physics) but didn’t explore it further than naming it because he was a man in a hurry, eager to make some money. He did this at his Menlo park labs, the first commercial lab made to make inventions, which was a model for Bell Labs. Bell Labs, an invention factory and Nobel Prize factory, was where Shockley thought of the semiconductor, and invented it. Later leaving in a hurry, eager to make his own fortune. He was a terrible manager, managed to attract and then repel the most brilliant minds of his day, who quit and formed their own company. Not because he was an anti-democratic racist eugenicist, but because they couldn’t get anything done with him in charge. Then those brilliant minds quit their company and formed their own companies, repeating the process, dividing like cells to eventually grow into the organism known today as Silicon Valley. It’s a story of immigrants, invention, idealism, anti-trust law, and practicality that is very American, and was fun to share. I tried to be controversial with the title “This could only have happened in America”. I did this to be provocative and try to get some reaction or pushback, but Kazakhs are too polite to push back. However, the more I thought about it, the more I realized the title was pretty accurate. Core American values like free speech, irreverence to title and position, meritocratic operations, our openness to outsiders and outside ideas . . . these were necessary, and almost sufficient, ideas that had to be a part of the culture that created the world’s greatest engineering achievement. This talk is my attempt to try to tie American values, the American 250th anniversary, and semiconductors together. Happy Birthday America!

    Tiny Tapeout - Matt Venn

    Matt is a force of nature in open silicon, and this interview is the second in our series on open silicon (see wafer.space first!). First, Matt is the creator of the Zero to ASIC Course, which has taken thousands of engineers, students, and makers from complete beginners to people who have actually taped out their own chips. Second, Matt is the founder of Tiny Tapeout, a platform that has put nearly 3,000 chip designs into real silicon, and in the process built what might be the most accessible on-ramp to custom chip design that’s ever existed. Together, those two things form a kind of end-to-end pipeline: learn to design, then actually build a real chip that no one else has really pulled off before. Along the way, Matt has built a sprawling empire of STEM education focused on semiconductors, with content spanning technology, education, and the semiconductor industry. From Zero To ASIC Custom chip design has often been viewed as an exclusive realm reserved for seasoned engineers and large corporations. However, as Matt explains, this landscape is changing rapidly; in part because of pioneering work done by Efabless and wafer.space (previous episode here). His services require no expensive tools, no NDAs and no massive non-recurring engineering (NRE) costs. Zero to ASIC started as a course; Matt put a call up online for a course offering to help students walk through making a chip design, using the Google Open Chip Program at Skywater’s foundry. His call to action immediately recruited 300 students to the course, which has grown to use different foundries and technologies. Over the last few years, Matt has built Zero to ASIC into an achievable path to custom chip design, developing the resources and community surrounding this field. Tiny Tapeout Tiny Tapeout gets open-source designers a tiny bit of real-estate on a wafer coming out of a real fab. While Matt started sending Zero to ASIC students through the Google project, he quickly switched to Efabless and ultimately wafer.space to run student designs. With the tools they’ve created, the work to design a chip can be done right in the browser, circumventing the need to install tools. Matt’s ultimate vision: chip design becomes as straightforward and widespread as PCB prototyping, fueled by open-source innovation and collaborative effort. chip design becomes as straightforward and widespread as PCB prototyping, Matt emphasizes the crucial role of accessible tools, the community’s contribution to open IP libraries, and the importance of democratizing access to chip fabrication technology. Tiny Tapeout is cheap enough you can just throw it on a credit card. What will the world look like with 10x more chip designers? By lowering the price (and hassle) by 10x, Matt enables a world where every undergrad can tape out their own chip.. Advice to a Young Engineer Matt’s advice to a talented, curious 22-year-old electrical engineering graduate: just do it. Get on the next tapeout! To learn, nothing beats doing. And Tiny Tapeout enables any student to participate in designing chips from end-to-end. Navigating the world of custom chip design may seem daunting, but with the right resources and community support, it can be an accessible and rewarding journey. Students can start with basic projects, utilize the free lessons on Matt’s website, and engage with the community . . . anyone can explore the possibilities of ASIC design.

    wafer.space - Tim 'mithro' Ansell

    In this episode, Tim ‘mithro’ Ansell shares his journey from software engineering to leading innovations in hardware, including open source silicon and most recently, founding wafer.space. Tim shares with us how open source principles are transforming the semiconductor industry, lowering barriers to entry, and enabling a new wave of innovation and entrepreneurship. “Open source is fundamentally transforming hardware.” We talk about how lowering costs and increasing accessibility can revolutionize the industry and inspire and empower a new wave of creators. Wafer Space wafer.space arose from the ashes of open silicon leader Efabless; when the pioneering firm shut down, Tim sprang into action, founding wafer.space to fill the void in the open silicon community. “Cost strategies are key to democratizing hardware.” In this episode we dive deep on the business model for open silicon, and how wafer.space is learning from history, and building back better. Wafer space offers silicon to anyone; the platform effectively removes the "wealth barrier" to custom silicon, making it as easy to order a chip as it is to order a custom PCB. Wafer.space’s second run has just opened up on CrowdSupply, so if you’ve always wanted to create your own semiconductor, now is your chance!

    Bringing Semiconductors to Kazakhstan

    I live in Almaty Kazakhstan. It’s not known as a hotbed of semiconductors (yet). When I first met Nursultan Kabylkas, and learned his background, I had to hear his story. This is the story of how one professor led a team of students to design the first chip in Kazakhstan's history, and in doing so, may have birthed a whole new national industry. TL:DR: * The Win: Kazakhstan’s first student-designed RISC-V chip. * The Strategy: Skipping the “fab-first” trap by specializing in verification via Texer.AI and Reasonbase.io * The Takeaway: Strategy + intellectual capital > Physical capital. You don’t need a fab to own a piece of the global supply chain. Kazakhstan’s First Chip Nursultan’s journey began at AMD in the United States, where he worked on silicon verification. When he returned to Kazakhstan in 2023 to teach engineering, he found a desert; the local semiconductor landscape was limited mostly to FPGA programming and encryption devices. When he shared his dream of bringing "real" silicon design to the country, he was met with skepticism. In his own words, he was laughed at. Most people jumped straight to the "billion-dollar fab" problem, assuming that without a massive manufacturing plant, the industry couldn't exist. Nursultan kept looking for an inspiring project to give his students a hands on project, a project that would move the needle through talent rather than infrastructure. Realizing that the key to developing an ecosystem here needed to start with talent, Nursultan focused in on design and verification. He found his catalyst in the “One Student, one Chip Initiative” from the Chinese Academy of Sciences. The program gave him a framework to get started, and after recruiting some enthusiastic students at Nazarbayev University they began designing the first chips. Through a partnership with a Chinese fab, the team got space on Multi-Project Wafer (MPW) and received back their RISC-V general purpose processor. The project went viral, the media caught on, and the project gained national attention. The project completely shifted the conversation, as Nursultan puts it, Before people were laughing . . . but after the chip came back, people started pointing me in different directions and mechanisms . . . The conversation changes from ‘It’s impossible’ to ‘How do we scale it?’ From the beginning, Nursultans’ vision has looked beyond the academic track, with a plan to build something even bigger in Kazakhstan. Bootstrapping the Ecosystem Nursultan didn't just want a trophy for the university trophy case; he wanted a self-sustaining industry. To turn this academic momentum into a commercial reality, he and his team launched Texer.AI, a verification company designed to employ the very students who went through his program. Further along, he also co-founded ReasonBase.io, a similar company bridging the SF Bay Area and Astana, to apply verification logic to other industries. By building a company around the chip’s success, Nursultan has created a “revolving door” between the classroom and the market. Through Texer.AI, specialized publications, and local conferences, he is guiding students directly into high-value engineering roles. This is bootstrapping at its finest: using a single successful project to fund the talent pipeline that will power the next ten projects. The Verification Specialization The engine driving this revolving door is a deliberate choice to skip the “fab-first” mentality. The strategy is clever: specialize in Verification. In the semiconductor world, verification is the rigorous process of mathematically proving a design works before a single dollar is spent on manufacturing. Verification offers a low-barrier, high-margin entry point. It requires mastery of complex tools and logic rather than multi-billion dollar cleanrooms. This “capital-efficient” on-ramp allows a startup like Texer.AI to establish global credibility and attract international partnerships without needing a local factory. By focusing on high-skill employment first, Nursultan’s vision for Kazakhstan is seeding a talent pipeline that is far more essential to long-term growth than any piece of hardware. Kickstarting a Global Blueprint This story carries a resonance far beyond Almaty, especially as more nations chase the dream of “semiconductor sovereignty.” Nursultan’s path provides a blueprint for emerging economies: you don’t need a massive capital investment to join the global supply chain. Innovation can start with niche expertise. By focusing on segments like design, verification, or encryption, a country can build its capabilities incrementally. Shifting the focus away from the “full manufacturing plant” requirement opens doors for any economy with a strong mathematical and engineering foundation to develop a resilient, sovereign industry. Shifting from the assumption that you need a full manufacturing plant to participate in semiconductors opens pathways for emerging economies to develop a sovereign and resilient industry. Nursultan’s vision for Kazakhstan, an approach of cultivating verified processor design and leveraging open-source tools exemplifies how targeted, skill-based initiatives create foundational assets for broader industry development. Kazakhstan’s Future Ultimately, the future of the Kazakh ecosystem relies on expanding these specialized clusters. By starting with a simple RISC-V processor and moving into complex supply chain applications, Nursultan has proven that the “impossible” is actually just a series of small, iterative steps. Creating a core niche and nurturing the startups within it fosters a self-reinforcing cycle of talent and investment. Kazakhstan is no longer “ecosystem absent”—it is on its way to becoming a vibrant, sustainable innovation hub, one verified line of code at a time.
