Emulating production environments presents significant challenges, particularly regarding the needs of probers and handlers. This paper introduces a versatile software solution designed to emulate the GPIB system on any Teradyne platform. This agnostic software can read various types of log files and replaces the NI GPIB library to send accurate responses based on the created logs. We will explore multiple use cases, including enhancing driver development, implementing regression and reliability tests, and testing products such as TEMS in production modes within a “production emulation environment.” Additionally, this software aids product engineers in testing their programs in customer production environments. The emulator facilitates testing of tester software, various products, and accelerates the deployment of test programs in customer production settings.
