Teardown Session 56: wafer.space with Tim Ansell

Join Crowd Supply’s Helen Leigh for a conversation with Tim Ansell about wafer.space, a new way for chip designers to easily turn a design into real, working chips.

About Our Guests
Tim “mithro” Ansell builds the bridges that make open silicon real. At Google, he helped release the SkyWater SKY130 open-source PDK and launched the Open MPW shuttle program; in FPGAs, he started SymbiFlow (now F4PGA under CHIPS Alliance) to enable vendor-agnostic, fully open flows. He’s also behind hacker-favorite boards Tomu and Fomu. Today, Tim continues pushing affordable, open fabrication for ASICs and FPGAs—empowering anyone to take a chip from idea to working silicon.

Leo Moser is an open-source silicon advocate and aspiring chip designer with tapeouts on all three major open source PDKs. He obtained his Master’s degree at Graz University of Technology, majoring in microelectonics and IC design. In his work, he designed Greyhound, a RISC-V SoC with tightly coupled FABulous eFPGA fabricated on IHP’s SG13G2 process. Previously, Leo worked at Efabless, where he focused on PDK enablement for the IHP Open Source PDK and on analog automation with CACE. He is excited about the future of the free and open-source silicon community.
