MPW3 submitted!
We submitted for MPW3! The tapeout date was delayed by a couple of weeks due to issues with the toolchain.
Update!
We received silicon in June 2023 (18 months later!) and I was able to get both my designs partially working.
MPW3
We had 7 new submissions from the course, 4 repeats from MPW1 and 2 with fixed clock trees, a new wishbone demo from me and the OpenRAM block.
We also had some people course make personal applications for a whole chip:
- Exor’s project contains two sudoku accelerator modules on the wishbone bus: https://platform.efabless.com/projects/428
- Paweł’s memory tester: https://platform.efabless.com/projects/501
- Sean’s pretrained handwriting recognition neural network: https://platform.efabless.com/projects/486
- An Analogue op-amp submission by Marcus that was kindly included in this project: https://platform.efabless.com/projects/406
The github repo for the group submission is here: https://github.com/mattvenn/zero_to_asic_mpw3
And the Efabless project is here: https://platform.efabless.com/projects/392
To see how I put the application together check here.

Multi Project Tools
The multi project tools have continued to improve:
- Added some new tests
- Optional ports, which means you can turn off the ones you don’t want, allowing smaller macros
- Support for different size macros
- Added OpenRAM instance for fast local memory
- Auto generate the cover image
- Support for MPW3 OpenLane tooling
- Can fetch all the project’s repos
This is what I do to build the project:
./multi_tool.py --config projects.yaml --force-delete --clone --copy-gds --generate-doc --annotate --create-openlane-config --openram
This:
- clones all the repos
- copies the GDS, LEF and Verilog to the right place
- generates doc and annotated image
- generates the macro positiioning and OpenLane config
- includes OpenRAM support
OpenRAM support
I’d like to say thanks to Paweł for all his work on integrating OpenRAM. It was much harder than it should have been and it wouldn’t have got done without him. I’ll be making an OpenRAM tutorial soon to help document how to use it.
