Dag Lem 39fea32c6e Add support for packed multidimensional arrays

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.

Dag Lem fb7f3bb290 Cleaner tests for RTLIL cells in struct_dynamic_range.sv 2023-05-04 14:28:21 +02:00
Dag Lem ad437c178d Handling of attributes for struct / union variables 
(* nowrshmsk *) on a struct / union variable now affects dynamic
bit slice assignments to members of the struct / union.

(* nowrshmsk *) can in some cases yield significant resource savings; the
combination of pipeline shifting and indexed writes is an example of this.

Constructs similar to the one below can benefit from (* nowrshmsk *), and
in addition it is no longer necessary to split out the shift assignments
on separate lines in order to avoid the error message "ERROR: incompatible
mix of lookahead and non-lookahead IDs in LHS expression."

    always_ff @(posedge clk) begin
        if (rotate) begin
            { v5, v4, v3, v2, v1, v0 } <= { v4, v3, v2, v1, v0, v5 };

            if (res) begin
                v0.bytes <= '0;
            end else if (w) begin
                v0.bytes[addr] <= data;
            end
        end
    end

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 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.

Brett Witherspoon 979053855c sv: improve support for wire and var with user-defined types 
- User-defined types must be data types. Using a net type (e.g. wire) is
  a syntax error.
- User-defined types without a net type are always variables (i.e.
  logic).
- Nets and variables can now be explicitly declared using user-defined
  types:

    typedef logic [1:0] W;
    wire W w;

    typedef logic [1:0] V;
    var V v;

Jeff Wang 249876b614 support using previously declared types/localparams/params in package 
(parameters in systemverilog packages can't actually be overridden, so
allowing parameters in addition to localparams doesn't actually add any
new functionality, but it's useful to be able to use the parameter
keyword also)
