ABSTRACT:
In at least one hardware definition language (HDL) file, at least one design entity containing a functional portion of a digital system is specified. The design entity logically contains first and second latches each having a respective plurality of different possible latch values. With one or more statements, a first Dial instance is associated with the first latch and a second Dial instance is associated with the second latch. A setting of the first Dial instance thus controls which of the plurality of different possible values is loaded in the first latch, and a setting of the second Dial instance controls which of the plurality of different possible values is loaded in the second latch. With a statement, a Register instance is concurrently associated with both the first and the second latches, such that a setting of the Register instance controls the latch values loaded in both the first and second latches.
