  • Method of recording and replaying call frames for a test bench
    Patent number: 8924912
    Abstract: A computer-implemented method to debug testbench code of a testbench associated with a circuit design by recording a trace of call frames along with activities of the circuit design. By correlating and displaying the recorded trace of call frames, the method enables users to easily trace as execution history of subroutines executed by the testbench thereby to debug the testbench code. In addition, users can trace source code of the testbench code by using the recorded trace of call frames. Furthermore, users can debug the testbench code utilizing a virtual simulation, which is done by post-processing records of the virtual simulation stored in a database.

  • METHOD OF RECORDING AND REPLAYING CALL FRAMES FOR THE TESTBENCH
    Publication number: 20110283247
    Abstract: A computer-implemented method to debug testbench and the associated circuit design by recording a trace of call frames along with the activities of the circuit design. By correlating and displaying the recorded call frames, the method enables users to easily trace the execution history of the subroutines and debug the testbench code. In addition, users can trace the source code of the testbench by using the trace of call frames. Furthermore, users can debug with a virtual simulation, which is done by post-processing the simulation records stored in a database.
