Abstract
Chisel and Verilator provide an open-source stack for digital design. For ASIC synthesis, we have open-source tools like OpenROAD, Yosys, and Magic. OpenROAD is a project to
deliver an end-to-end silicon compiler in open source. The aim is to “democratize hardware design” by providing an automated layout generation flow from a design in RTL to GDS files used to produce silicon. Google and Efabless offer free production of chips in a multi-project wafer if the project is available in open source. In this paper, we report our experience in using the open-source tool flow from Chisel to chips with two designs: a small processor using only on-chip resources and a RISC-style processor, called Patmos, with extra external main memory. We have successfully taped out the Patmos processor for the multiproject waver MPW7 from Efabless.
