Jannis Harder	55ad3fe6c7	xprop tests: Make iverilog invocation more portable	2023-02-13 16:54:11 +01:00
Jannis Harder	2a68eee5f1	xprop: Test fixes and abort on test failure ... Use `$finish(0)` to silently exit even when using recent iverlog versions. Run `write_verilog -noexpr` before `write_verilog` as the latter can modify the design. This also enables checking the tests results, as xprop should be in a state where the existing tests pass.	2023-02-13 14:05:16 +01:00
Jannis Harder	6d021f04d4	tests: Fix path of yosys invocation in xprop tests ... For now xprop test failures are still expected and ignored, but without this change, they did not even run unless the yosys build was in path.	2023-02-10 19:17:16 +01:00
Jannis Harder	ce708122a5	New xprop pass to encode 3-valued x-propagation using 2-valued logic	2022-11-30 19:01:28 +01:00
