Abstract:
1. A method of analyzing scan tests of an IC device, comprising: processing data of a device definition, a test program definition, and test execution results to produce cross-reference data interrelating signals, scan chains, test execution results and steps of the test program; rendering views for presentation on a display, the views including at least a cyclized test view, a procedural test program view, and views of a signal vector, scan state, and scan vector; selectively presenting the views on the display; navigating responsive to a user navigation input from a location selected in a current view to a correlated location in a user directed other of the views based on the cross-reference data; modifying the test program definition in response to user editing inputs; re-executing the modified test program; acquiring test execution results from execution of the modified test program; and repeating the above-recited processing, rendering, presenting and navigating steps based on the modified test program for analyzing the modified test of the IC device.
