TetraMAX Description

TetraMAX™ ATPG is the leader for automatically generating high quality manufacturing test vectors. As a critical part of TetraMAX, the interoperability flow between Synopsys' TetraMAX and Source III's VTRAN® allows for quick and easy translation of ATPG-generated test vector data to many popular device test program formats, as well as simulation testbench formats.

Challenge

During TetraMAX's product beta in fall 1998, the software development and applications team faced their share of challenges. As a key member of the corporate applications team, Julie Villar, was tasked with generating market interest at major foundries including Fujitsu, Toshiba, LSI, NEC, and Texas Instruments. However, with the merger of 3 ATPG products, Julie and her team realized they had a major problem on their hands. They needed to decide on which test vector formats to support based on a myriad of choices already supported by all three ATPG products. Not only that, they had to accurately translate those vectors from their STIL-based TetraMAX product to target many tester platforms. With the final release date looming in the following quarter, Julie's team needed to find a solution quickly.

Strategy

While searching for the solution, the TetraMAX team quickly ruled out any internally developed translators given the requirements of time-to-market, quality, and multiple test language format support. Synopsys had to look elsewhere for a solution. As it turns out, they didn't have to look very far because the Test Compiler product acquired by Synopsys was already using a solution from Source III. After several discussions between the TetraMAX team and Source III, it was clear that Source III's VTRAN® product was the critical "link" for TetraMAX, so Synopsys decided to look no further. "Without VTRAN®, IC customers could not pass their ASIC designs to foundries", said Julie. "Source III was the only vendor with STIL support - providing us with an overall solution that no one else could."

Implementation

As the TetraMAX team began to interface to VTRAN®, the translation worked immediately - giving the team final assurance that a solution was found. Source III's VTRAN® was customized to read TetraMAX's WGL and STIL test format while providing a translation path to many test vector formats such as Toshiba TSTL2, Texas Instruments TDL91, and Fujitsu FTDL, and Verilog VCDE (input only), testbench formats including Verilog and VHDL and target tester formats from Credence, Teradyne, and Agilent.

Results

By providing a path to several foundry formats, Source III's VTRAN® helped TetraMAX expand its customer reach. In doing so, VTRAN® paved the way for TetraMAX to reach market acclaim. The result is the "Best in Test" award given to TetraMAX in 2000, which honors important and innovative new products in the electronics test and measurement industry.
