Detailed Description

An unpacked SystemVerilog type.

Unpacked types are a second level of types in SystemVerilog. They extend a core unpacked type with a variety of unpacked dimensions, depending on which syntactic construct generated the type (variable or otherwise). The core unpacked types are:

• Packed types
• Non-integer types: shortreal, real, realtime
• Unpacked structs and unions
• string, chandle, event
• Virtual interfaces
• Class types
• Covergroups
• Unpacked named types
• Unpacked type references

The unpacked dimensions are:

• Unsized ([])
• Arrays ([x])
• Ranges ([x:y])
• Associative ([T] or [*])
• Queues ([$] or [$:x])

classof()

static bool circt::moore::UnpackedType::classof ( Type  type )

inlinestatic

Definition at line 84 of file MooreTypes.h.

getBitSize()

std::optional< unsigned > UnpackedType::getBitSize

(

)

const

Get the size of this type in bits.

Returns None if any of the type's dimensions is unsized, associative, or a queue, or the core type itself has no known size.

getDomain()

Domain UnpackedType::getDomain

(

)

const

Get the value domain of this type.
