Refer to README for this sample project documentation.
You will need a Linux environment with Docker. Once you have that, you can set things up:
mkdir -p deps export OPENLANE_ROOT=$(pwd)/deps/openlane_src # you need to export this whenever you start a new shell export PDK_ROOT=$(pwd)/deps/pdks # you need to export this whenever you start a new shell export PDK=gf180mcuC # you can also use sky130B
These steps are included in
activate-caravel.sh, which you can just source.
Next, do a one-time setup of the project.
Next, perform the synthesis, which will take anywhere between 30 minutes and 3 hours:
When it's done, the resulting files will be in
You can run the testbench using iverilog, which will generate a
You can then inspect the
.vcd file by using a tool such as
gtkwave to view
