Test Designer won the 1999  "Best in Test" award, chosen by the editors of Test & Measurement World!  

Test Designer was among only 10 products selected for the award, which recognized the best test products released over the past year. 

Test Designer is today's only complete design simulation and verification system for analog, mixed-signal and mixed-systems design, which also features full fault and test synthesis capability. For the first time ever, engineers can efficiently design, simulate and test complex analog and mixed-signal circuitry in the design cycle. Test Designer is an industry first, delivering the only comprehensive and structured approach to Analog and Mixed-Signal Design Analysis and Test Automation (AMDTA).

Test Designer encompasses every capability of the ICAP/4 Professional product line. It includes analog, digital and mechanical elements, as well as behavioral and C-code AHDL modeling abstraction. Automated fault injection, test development and isolation strategies for detecting faults are key additions to this unprecedented offering. The user can easily pair different circuit configurations with various analyses to create test setups, assign measurements (i.e., peak-to-peak, RMS, rise time, etc.) at prescribed design nodes, and define corresponding pass/fail limits for evaluating the detection of faults.

Test Designer computes fault detections for an entire suite of tests without the need for operator intervention. It first synthesizes faults throughout the design. Then it creates an extensive fault universe and fault tree for isolating faults in the fastest and most efficient manner. A weighted test-sequencing algorithm is run, which ultimately generates a test strategy report of detected faults and quality of fault coverage. This powerful capability extends SPICE well beyond today's simulation boundary, adding complete development for automatic fault and test program design. Test Designer helps ensure minimal product fallout during real production test by initiating its power early in the design cycle. It also greatly reduces test development costs by automating complex test sequencing processes, and it provides pseudo-code for use in automated test equipment.
