To generate HDL for all adder structures at a certain width, simply
make compile WIDTH=<desired width>
To run synth on all adder structures at a certain width, simply
source sourceme
make synth WIDTH=<desired_width>
This will save all synthesis results to the outputs folder. Note that re-running synthesis with a different width will not override previous results. Re-running synthesis with the SAME width WILL OVERRIDE previous results.
Once synthesis is done, pnr can be run with
source sourceme
make pnr WIDTH=<desired_width>
This will make full back-ups of all PnR runs. Note that re-running PnR with a different width will not override previous results. Re-running PnR with the SAME width WILL OVERRIDE previous results.
To run testbenches and generate VCD for all adder structures at a certain width, simply
make vcd WIDTH=<desired_width>
To automatically parse PPA results for all adder structures at a certain width, run PnR, and then
make results WIDTH=<desired_width>
Both synth and PnR can be run in parallel, with parallel_synth and parallel_pnr respectively.
