Corelis, Inc., a leading supplier of high-performance JTAG test and measurement tools, announced today the successful integration and deployment of the ScanExpress JTAG Embedded Test (JET) functional test system at the production facilities of QSC Audio Products, LLC in Costa Mesa, California. QSC, a leader and pioneer in professional audio products for over four decades, implemented Corelis ScanExpress JET alongside ScanExpress boundary-scan tools to increase Flash programming rates and total test coverage during manufacturing.
QSC’s Q-Sys™ Integrated System Platform was selected as the initial target platform for ScanExpress JET deployment. Q-Sys is a complete routing, processing, and control solution for large scale applications built around the Q-Sys Core—a centralized processor responsible for managing audio processing and control functions. Rising demand for Q-Sys production led QSC to a point where test and programming times became an increasing bottleneck.
“QSC had been successfully using Corelis boundary-scan test systems in production for almost a decade now,” explains Corelis Senior Technical Marketing Engineer, Ryan Jones. “Integration with JET offered the next logical step to reduce their test time and meet their growing production requirements. It demonstrates our software’s ability to grow alongside our customers.”
Corelis applications engineers were quickly able to implement JET technology in QSC’s Q-Sys test process. QSC Digital Test Engineer, Jose Gutierrez comments, “As far as product support goes, Corelis gets a 1000%. We were quite pleased with the ease of JET integration. Corelis technical support really went out of their way to offer assistance with getting things up and running.”
Combined with QSC’s boundary-scan tests, JET added blazingly fast ISP as well as at-speed RAM tests. According to Gutierrez, “Test time per unit was reduced from 10 minutes just for programming the Flash down to around 2 minutes. This was exactly the solution we needed.”
