Method and system for reducing storage and transmission requirements for simulation results

A system for creating compact result data sets of simulation processing of a hardware description language (HDL) model, said system comprising:

• means for receiving a HDL model including a plurality of design entities and a plurality of count event registers, wherein each of said count event registers is associated with a respective instance of an event of interest within said HDL model, wherein said plurality of count event registers includes at least first and second count event registers for counting occurrences of a same replicated event generated within different instances of a same design entity having a same hierarchical level within the HDL model;
• means for receiving a correlation data structure indicating which of said plurality of count event registers are associated with instances of said same replicated event;
• means for performing simulation processing on said HDL model;
• means for maintaining within each of said plurality of count event registers a respective count value representing a number of times an associated event instance occurred during simulation of said HDL model;
• means for summing count values of said first and said count event registers in accordance with said correlation data structure to obtain an aggregate count value;
• and
• means for outputting a non-hierarchical count event data packet containing said aggregate count value.

A program product, comprising:

• a computer usable medium;
• a simulation client within said computer usable medium, said simulation client including:
• instruction means for receiving a HDL model including a plurality of design entities and a plurality of count event registers, wherein each of said count event registers is associated with a respective instance of an event of interest within said HDL model, wherein said plurality of count event registers includes at least first and second count event registers for counting occurrences of a same replicated event generated within different instances of a same design entity having a same hierarchical level within the HDL model;
• instruction means for receiving a correlation data structure indicating which of said plurality of count event registers are associated with instances of said same replicated event;
• instruction means for performing simulation processing on said HDL model;
• instruction means for maintaining within each of said plurality of count event registers a respective count value representing a number of times an associated event instance occurred during simulation of said HDL model;
• instruction means for summing count values of said first and said count event registers in accordance with said correlation data structure to obtain an aggregate count value;
• and
• instruction means for outputting a non-hierarchical count event data packet containing said aggregate count value.
