Jannis Harder fb1c2be76b verilog: Support void functions 
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.

Jannis Harder 390d1c583a verific: Fix enum_values support and signed attribute values 
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.

Merge pull request #3682 from daglem/struct-member-out-of-bounds 
Out of bounds checking for struct/union members
 2023-03-10 16:14:56 +01:00
Dag Lem 0d3423ddea Index struct/union members within corresponding wire chunks 
This guards against access to bits outside of struct/union
members via dynamic indexing.

Dag Lem c1e12877f0 Support for data and array queries on struct/union item expressions 
For now, $bits, $left, $right, $low, $high, and $size are supported.

Dag Lem 777c589e85 Handle range offsets in packed arrays within packed structs 
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.

Jannis Harder dd8b412833 simplify: Do not recursively simplify AST_CELL within AST_CELLARRAY 
Otherwise the AST_CELL simplification uses the wrong celltype before the
AST_CELLARRAY simplification has a chance to unroll it and change it to
the $array celltype.

Zachary Snow 71e7e09092 verilog: Support module-scoped task/function calls 
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.
