摘要:
Methods, data processing systems, and program products supporting the insertion of clone latches within a digital design are disclosed. According to one method, a parent latch within the digital design is specified in an HDL statement in one of the HDL files representing a digital design. In addition, a clone latch is specified within the digital design utilizing an HDL clone latch declaration. An HDL attribute-value pair is associated with the HDL clone latch declaration to indicate a relationship between the clone latch and the parent latch according to which the clone latch is automatically set to a same value as the parent latch when the parent latch is set. Thereafter, when a configuration compiler receives one or more design intermediate files containing the clone latch declaration, the configuration compiler creates at least one data structure in a configuration database representing the clone latch and the relationship between the clone latch and the parent latch.
