Method and apparatus to efficiently access modeled memory in a logic simulation hardware emulator

摘要

The present invention enhances the Direct Access Stimulus (DAS) interface presently employed within a logic simulation hardware emulator to provide efficient random access to all logic arrays present within a logic model while the emulator is actively cycling. The present invention achieves this by introducing a set of special DAS array port logic within the logic model. This new port logic interfaces with a set of connections on the DAS card interface and provides the control program with efficient random accessibility to all arrays within the design under test (i.e., the logic model).
