Vl-union

A SystemVerilog union datatype, or an array of unions.

This is a product type, introduced by deftagsum in support of vl-datatype.

Fields

members — vl-structmemberlist

The list of union members.

packedp — booleanp

Roughly: says whether this union is packed or not, but warning! this should normally not be used as it has the same problems as packedp for structs; see vl-struct.

pdims — vl-dimensionlist

Packed dimensions for this union type.

udims — vl-dimensionlist

Unpacked dimensions for the union type. See also vl-struct and the notes about unpacked dimensions there.

signedp — booleanp

Roughly: says whether this union is signed or not, but warning! this should normally not be used as it has the same problems as signedp for structs; see vl-struct.

taggedp — booleanp

Says whether this union is 'tagged' or not.

Subtopics

A single member of a struct or union.
