Hi Wilson,

I'm having a rough time with the SigParser's "var" callback. I'm trying to use this callback to find typedef declarations of packed structs eg:

  typedef struct packed {
     bit yes;
     bit no;
  } type_decision; 

In order to find all this user-defined datatype declarations I'm using the "var" callback, and looking for a "typedef" keyword with "struct" datatype.
The problem I'm having is that sometimes a callback is made for the internal fields of a struct, and those fields are marked as "typedefs" of "struct" datatype.

I'm attaching a test case to clarify the issue.
On Verilog-Perl version I'm running (3.210) the printed outputs of the testcase are:

Parsing test_pkg.sv
Struct found: name=type_struct1, objof=package, data_type=struct;
Struct found: name=field_bit, objof=package, data_type=struct;
Struct found: name=field_struct1, objof=package, data_type=struct;
Struct found: name=type_struct2, objof=package, data_type=struct;
End parsing test_pkg.sv

Note that "field_struct1" and "field_bit" are fields of another structure datatypes.

To run the testcase:

myparser.pl -file=test_pkg.sv

Thanks in advance,
David
