Detailed Description

A packed SystemVerilog type.

Packed types are the core types of SystemVerilog. They combine a core packed type with an optional sign and zero or more packed dimensions. The core packed types are:

Integer vector types: bit, logic, reg
Integer atom types: byte, shortint, int, longint, integer, time
Packed structs and unions
Enums
Packed named types
Packed type references

The packed dimensions can be:

Unsized ([])
Ranges ([x:y])

Note that every packed type is also a valid unpacked type. But unpacked types are not valid packed types.
