Method, system and program product for specifying a configuration of a digital system described by a hardware description language (HDL) model

摘要

A method of specifying a configurable digital system is disclosed. According to the method, at least one design entity containing a functional portion of a digital system is specified in at least one hardware definition language (HDL) file. The design entity logically contains a configuration latch having a plurality of different possible configuration values that each corresponds to a different configuration of the functional portion of the digital system. A statement in the HDL file associates a Dial entity with the design entity. The Dial has a Dial input, a Dial output, and a mapping table indicating a mapping between each of a plurality of possible input values that can be received at the Dial input and a respective corresponding output value for the Dial output. The output value specifies which of the plurality of different possible configuration values is loaded into the configuration latch.
