Jannis Harder	331ac5285f	tests: Run async2sync before sat and/or sim to handle $check cells ... Right now neither `sat` nor `sim` have support for the `$check` cell. For formal verification it is a good idea to always run either async2sync or clk2fflogic which will (in a future commit) lower `$check` to `$assert`, etc. While `sim` should eventually support `$check` directly, using `async2sync` is ok for the current tests that use `sim`, so this commit also runs `async2sync` before running sim on designs containing assertions.	2024-02-01 16:14:11 +01:00
Zachary Snow	b6af90fe20	verilog: fix sizing of constant args for tasks/functions ... - Simplify synthetic localparams for normal calls to update their width - This step was inadvertently removed alongside `added_mod_children` - Support redeclaration of constant function arguments - `eval_const_function` never correctly handled this, but the issue was not exposed in the existing tests until the recent change to always attempt constant function evaluation when all-const args are used - Check asserts in const_arg_loop and const_func tests - Add coverage for width mismatch error cases	2021-02-21 15:44:43 -05:00
