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 an 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.
