Google's Plan to Make Chip Development More Like Open Source Software

From Google's Open Source blog:The Google Hardware Toolchains team is launching a new developer portal, developers.google.com/silicon, to help the developer community get started with its Open MPW shuttle program. This will allow anyone to submit open source integrated circuit designs to get manufactured at no-cost. Since November 2020, when Skywater Technologies announced their partnership with Google to open source their Process Design Kit for the SKY130 process node, the Hardware Toolchains team here at Google has been on a journey to make building open silicon accessible to all developers. Having access to an open source and manufacturable PDK changes the status-quo in the custom silicon design industry and academia: - Designers are now free to start their projects liberated from NDAs and usage restrictions - Researchers are able to make their research reproducible by their fellow peers - Open source EDA tools can integrate deeply with the manufacturing process Together we've built a community of more than 3,000 members, where hardware designers and software developers alike, can all contribute in their own way to advance the state of the art of open silicon design.... We need to go beyond cramming more transistors into smaller areas and toward more efficient dedicated hardware accelerators. Given the recent global chip supply chain struggles, and the lead time for popular ICs sometimes going over a year, we need to do this by leveraging more of the existing global foundry capacity that provides access to older and proven process node technologies.... By combining open access to PDKs, and recent advancements in the development of open source ASIC toolchains like OpenROAD, OpenLane, and higher level synthesis toolchain like XLS, we are getting us one step closer to bringing software-like development methodology and fast iteration cycles to the silicon design world. Free and open source licensing, community collaboration, and fast iteration transformed the way we all develop software. We believe we are at the edge of a similar revolution for custom accelerator development, where hardware designers compete by building on each other's works rather than reinventing the wheel.... To help you on-board on future shuttles, we created a new developer portal that provides pointers to get started with the various tools of the open silicon ecosystem: so make sure to check out the portal and start your open silicon journey!
