Synopsys announced the availability of Test Fusion technology with new test point functionality, providing design teams with powerful design-for-test (DFT) circuit modifications to reduce silicon test costs by an average of forty percent and increase defect detection while meeting design targets for power, performance, and area. Test Fusion ensures the test points avoid introducing routing congestion and minimize area impact, in contrast to traditional test point implementation techniques. RTL designers can easily deploy test points with a single step that automatically combines Synopsys’ SpyGlass DFT ADV testability analysis, DFTMAX design-for-test, and Synopsys synthesis products, then run TetraMAX II automatic test pattern generation (ATPG) to create efficient silicon manufacturing tests. The solution is fully certified to comply with the ISO 26262 automotive functional safety standard and is widely deployed among semiconductor manufacturers.
To meet lower cost and increasing quality requirements, semiconductor manufacturers seek new technologies to improve detecting defective silicon prior to shipment. Several industry segments, such as automotive, are challenged to meet manufacturing test cost goals while achieving quality levels for their integrated circuits (ICs) of less than one defective part per million. Synopsys test points assist meeting these requirements by modifying the design to improve the ability of TetraMAX II to generate silicon test programs. SpyGlass DFT ADV analyzes designs and determines the most optimal and effective locations for test points that both decrease test pattern volume and increase defect coverage. Test Fusion technology ensures DFTMAX and Synopsys synthesis tools work in combination to implement the test points at the selected locations while minimizing routing using physical design data. Furthermore, Test Fusion provides an unprecedented reduction of area and congestion by enabling multiple test points to share a single test register based on physical proximity.
