Design to test software solutions


Founded in 1979, TSSI merged with See Technologies in 1994 to form Summit Design. Summit then sold TSSI to Credence in 1997. TSSI then became an independent company again in 2005. The company serves the vector translation and pattern validation markets.

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.

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