CaseZ class
A special version of Case which can do wildcard matching via z
in
the expression.
Any z
in the value of a CaseItem will act as a wildcard.
Does not support SystemVerilog's ?
syntax, which is exactly functionally
equivalent to z
syntax.

Constructors
-
CaseZ(Logic expression, List<
CaseItem> items, {List<Conditional> ? defaultItem, ConditionalType conditionalType = ConditionalType.none}) -
Whenever an item in items matches expression, it will be executed, but
the definition of matches allows for
z
to be a wildcard.
Properties
- caseType → String
-
Returns the SystemVerilog keyword to represent this case block.
no setteroverride

conditionals
→ List<
Conditional> -
Lists of all
Conditional
s directly contained within thisConditional
(not including itself).latefinalinherited - conditionalType → ConditionalType
-
The type of case block this is, for special attributes
(e.g. ConditionalType.unique, ConditionalType.priority).
finalinherited
-
defaultItem
→ List<
Conditional> ? -
The default to execute when there was no match with any other CaseItems.
no setterinherited

drivers
→ List<
Logic> -
Lists all drivers, recursively including all sub-Conditionals drivers.
latefinalinherited
- expression → Logic
-
A logical signal to match against.
finalinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
-
items
→ List<
CaseItem> -
An ordered collection of
CaseItem
s to search through for a match to expression.finalinherited -
