The Tessent DefectSim product measures the defect coverage of any test applied to an analog or mixed-signal circuit. This tool enables a designer to improve the quality of analog and mixed-signal circuits during integrated circuit (IC) design by guiding design-for-test (DFT) and the selection of more effective manufacturing tests. It also enables test engineers to reduce test costs by showing which tests do not increase coverage and whether simpler or faster tests could achieve higher coverage. The tool satisfies the growing defect-coverage measurement requirement for automotive ICs set by Tier1 automotive suppliers in accordance with the ISO 26262 automotive functional safety standard.
The Tessent DefectSim tool works with Mentor's Eldo® and Questa® ADMS™ simulators to measure the likelihood-weighted percentage of opens, shorts, extreme variations, and user-defined defect or fault models that can be detected within a layout-extracted or schematic netlist. The Tessent DefectSim product combines many techniques, described in our peer-reviewed papers, to reduce total simulation time by many orders of magnitude compared to simulation of every potential defect in a flat layout-extracted netlist, without reducing simulation accuracy or the choice of tests.
"We are gratified to receive this industry recognition for an analysis tool that has taken many years to develop, and is the only general-purpose, analog fault simulator available commercially," said Stephen Sunter, engineering director for mixed-signal DFT at Mentor Graphics. "We thank the many customers who evaluated the Tessent DefectSim tool and provided so much constructive feedback to help ensure that their AMS designers will have the fault simulation capability that digital designers have had for 30 years and which has facilitated tremendous advances in automation for digital DFT and test generation."
