skywater130_decred_miner

Environment setup

Follow the steps at https://github.com/efabless/openlane#quick-start. Note that as of the time of this writing, the develop branch of open lane was used (i.e., git clone https://github.com/efabless/openlane.git --branch develop). If the docker is run manually, you'll need to specify rc5 instead of rc4.

After make test succeeds, proceed to check out step next.

Check out

cd openlane/designs
git clone https://github.com/SweeperAA/skywater130_decred_miner.git ./caravel
cd caravel
make uncompress

Build decred flow

At this point, there are two ways build the decred ASIC flow. At the time of this writing, each option has it's own deficiencies but you can get some intermediate results.

Option 1: Build the macro independent of the caravel chip harness user space area.

cd caravel/openlane
make decred_top

Option 2: Build the entire user space together with decred.

cd caravel/openlane
make user_project_wrapper
