An automated test harness creates a unified test framework that helped in instrument set-up, test-case running, data collection, waveform generation and analysis.
ASIC validation in the RF world comes with its own set of hurdles and challenges, with high-quality lab equipment, experience and know-how essential. A recently completed RF sub-system validation at S3 Semiconductors is presented in the form of a case study of the execution. The validation PCB design focussed on impedance matching and shielding RF signals from noise sources. We built up an efficient, automated test harness based on LabVIEW, MATLAB and python. This unified test framework facilitated instrument set-up, test-case running, data collection, traceability, plotting of measurements, waveform generation and analysis.
