Abstract

A code coverage tool can be made more useful if circuits of a specified function can be identified by their truth table. This knowledge can be used during code coverage testing to determine what circuits may not be covered during the appearance of specified input data configurations for such circuits. Forcing all circuits to a specified state and running the truth table data through them, when properly instrumented in emulation allows for determination of such specified functionality.
