  • Method and apparatus for recording and viewing error data generated from a computer simulation of an integrated circuit
    Patent number: 6163763
    Abstract: A method and apparatus for managing simulation results involve identifying errors within a group of simulation results so that the errors can be recorded into a database and viewed for analysis. In a preferred embodiment of the invention, distinct transactions within a group of simulation results are identified and recorded along with the identified errors. Recorded error-specific data and transaction-specific data are then utilized to graphically display the simulation results such that individual transactions identified within the simulation results are graphically distinct and such that errors occurring during a transaction are visually identified with the transaction. Recording and displaying error information and raising the level of abstraction of simulation results from cycles and signals to transactions enables easier simulation analysis and debugging.
