| # This patch is only applied if SymbiYosys isn't installed. Not sure if all |
| # `GrayCoderTestCase` will require it but it is probable all `FIFOFormalCase` |
| # will as SymbiYosys allows formal hardware verification. |
| # |
| # It isn't currently available in ChromiumOS and only 11 out of 605 tests are |
| # skipped so let's not depend on SymbiYosys for testing. |
