Title:
METHOD AND DEVICE FOR SIMULATING DIGITAL CIRCUIT
Document Type and Number:
Japanese Patent JP3731929
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To coordinate the operations of two separate simulators.
SOLUTION: A first simulator and a second simulator respectively increase the simulation time when they become active, and when signals responded by one of second circuit models are changed by the first simulator, the second simulator is used. Leaving from the second simulator can not be performed until further signal change is not performed any more by the second circuit model. In this stage, the final assertion value of the signals changed by the second circuit model is returned in a first model, and when the pending signal change is present inside the second simulator at the time of entering the second simulator in response to the signals from the first simulator, first simulator signals are put in a buffer until the pending signal change occurs.
