sv: support for parameters without default values - Modules with a parameter without a default value will be automatically deferred until the hierarchy pass - Allows for parameters without defaults as module items, rather than just int the `parameter_port_list`, despite being forbidden in the LRM - Check for parameters without defaults that haven't been overriden - Add location info to parameter/localparam declarations 2021-03-02 09:43:53 -06:00			`read_verilog -sv param_no_default.sv`
hierarchy: Without a known top module, derive all deferred modules This fixes hierarchy when used with cell libraries that were loaded with -defer and also makes more of the hierarchy visible to the auto-top heuristic. 2024-01-12 09:30:37 -06:00			`hierarchy -top top`

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. 2024-01-22 10:44:05 -06:00			`async2sync`
