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.
