Device Testing with Digital Pattern Instruments Course Overview

The Device Testing with Digital Pattern Instruments course enables Test and Validation Engineers to perform characterization and production test of semiconductor devices with digital pattern instruments. The course will focus on how digital pattern instruments and the Digital Pattern Editor can be leveraged to perform common device tests, with a focus on DUT communication, digital interface testing, and continuity and leakage testing. The course will guide the learner through the complete test workflow, from calibration and debugging to extending tests into a test executive.
