Functional test program generation through interactive graphics

A methodology and the implementation are described of a graphical waveform editor which is used to create functional test programs on an engineering workstation. The system has been implemented such that timing and test patterns can be created or customized for different target testers utilizing diverse timing technologies. The graphical waveform editor is described in the context of an integrated test-program generation environment. The features of the editor include timing and pattern editing, subroutine definition, time set selection, logic state definition and translation, synchronization, event definition and search, pattern differences and other similar functions. A summary of user experience and planned enhancements is presented
