* verilog: Fix const eval of unbased unsized constantsJannis Harder2023-04-201-1/+1
| | | | | | | | | | | | | | When the verilog frontend perfomed constant evaluation of unbased unsized constants in a context-determined expression it did not properly extend them by repeating the bit value. This only affected constant evaluation and not constants that made it through unchanged to RTLIL. The latter case was already covered by tests and working before. This fixes the const-eval issue by checking the `is_unsized` flag in bitsAsConst and extending the value accordingly. The newly added test also tests the already working non-const-eval case to highlight that both cases should behave the same.
* verilog: Support void functionsJannis Harder2023-03-202-1/+19
| | | | | | | The difference between void functions and tasks is that always_comb's implicit sensitivity list behaves as if functions were inlined, but ignores signals read only in tasks. This only matters for event based simulation, and for synthesis we can treat a void function like a task.
* verific: Fix enum_values support and signed attribute valuesJannis Harder2023-03-151-34/+33
| | | | | | This uses the same constant parsing for enum_values and for attributes and extends it to handle signed values as those are used for enums that implicitly use the int type.

| | | | | | | | | | | | | | This brings the metadata for packed arrays in packed structs in line with the metadata for unpacked arrays, and correctly handles the case when both lsb and msb in an address range are non-zero.

| | | | | | | | | | | | | | | | | | | | | | | | This is primarily intended to enable the standard-permitted use of module-scoped identifiers to refer to tasks and non-constant functions. As a side-effect, this also adds support for the non-standard use of module-scoped identifiers referring to constant functions, a feature that is supported in some other tools, including Iverilog.
