Edalize ASIC backend

[Edalize ASIC backend]

Affordable Open Source ASIC development and custom silicon has been a long-standing goal in the community. This will unlock innovation that has previously only been possible for the largest tech companies, allowing for the creation of deployable, trusted Open Source based hardware.

Step by step, this goal has come closer in the last few years as individuals, companies and academic institutions have filled in the missing pieces. Today we have a fully open source end-to-end flow for building open source ASIC - but the effort of on-boarding existing designs remains high. This project aims to provide an easy way to onboard existing gateware and full designs to an open source ASIC flow by creating a FuseSoC backend that targets this toolchain. This will enable a smoother transition from projects already running on FPGAs to also be targeting ASIC flows. It will also allow easier switching between different open source ASIC flows at the point when there are several alternatives to choose from.

In addition to the backend itself, a reference design containing SERV, the world’s smallest RISC-V CPU, will be run through the flow and committed to actual silicon. This will provide a way to guarantee a working flow and provide a simple but usable reference for everyone else looking to onboard their designs. Enabling and demonstrating this path will allow a fully trustworthy path for the fabrication of system-on-a-chip ICs, with no proprietary or closed tools as part of the flow and hence completely inspectable at all stages. This paves the road for other more complex FuseSoC-based open source silicon projects such as OpenTitan and SweRVolf.
