About Us

TSSI Building

Test Systems Strategies Incorporated (TSSI) is a leader in electronic design-to-test automation software solutions, headquartered in the beautiful Pacific Northwest of the United States.

Founded in 1979, TSSI continues to command the largest installed base in the vector translation and pattern validation markets.  Design and test teams of all sizes use our products to save time, cut costs, and dramatically decrease time to market.

One of TSSI's major contributions includes the invention of the Waveform Generation Language (WGL), the de-facto standard for ATPG (automatic test pattern generation) and tester interface.  WGL was one of the core languages contributing to the IEEE 1450 (STIL) standard.  WGL and STIL are both key standards in use today.

We provide innovative products and premier services for converting functional and structural simulation data from EDA (electronic design automation) output formats to ATE (automatic test equipment) program files. Our revolutionary pattern validation technologies offer design and test teams time and cost savings in pre- and post-silicon test program verification, debugging, and failure analysis.
