| # Tiny Tapeout submission (ttsky26d, sky130A). | |
| # | |
| # This directory has the layout of a Tiny Tapeout project repository | |
| # (info.yaml, src/, test/, docs/, .github/workflows/). src/ and test/ hold | |
| # copies of shared sources so the directory can be pushed as its own repository. | |
| # | |
| # make sync copy the shared RTL and testbench into src/ and test/ | |
| # make check-sync fail if a copy differs from its original (CI runs this) | |
| # make test UART testbench on the RTL (test/, divisor 2 and default) | |
| # make harden GDS with LibreLane 3.0.14 via tt-support-tools (needs the | |
| # LibreLane Nix shell; see README.md) | |
| # make gl-test the same testbench on the hardened gate-level netlist | |
