# Verific Test Cases
## Yosys Built-In
### Working
- `case`
- `clocking`
- `enum`
### Skipped
- `bounds`: checks top and bottom bound attributes, which are removed to avoid OpenSTA issues
- `memory_semantics`: relies on initial values being retained, which we do not want
- `rom_case`: relies on using Verific's frontend rather than GHDL
