Software entity for the creation of a hybrid cycle simulation model

Abstract

Disclosed is a software entity for constructing a Hybrid Cycle Simulation model comprising Compiled Data Units (CDUs) for use in design verification. The simulation model may contain a plurality of 1-cycle CDUs, optimized for simulation throughput, and 2-cycle CDUs, optimized for simulation accuracy, or a mixture thereof. Utilizing a netlist tool extracting hierarchical design source components for use, the construction checks that all inputs and outputs of any hierarchical design source components bind, and employs Object Traversal Directives for incorporating the selected CDUs into the simulation model. A data management method is used for tracking the validity of the components in the model. Additionally, a software entity (FACDDR) permits high bandwidth simulation of design components normally requiring cycle accurate simulation. FACDDR provides linkages for standard logic elements for abstracting one or more design interface components out of a cycle simulation environment and design interface emulation of an interface which interacts with a cycle simulation model through an API to extract present value of driving side signals of an interface and to set the cycle simulation model on the receiving side.
