Tessent

Tessent from Siemens EDA is the industry’s most comprehensive platform for design-for-test (DFT), production test, diagnosis, and silicon lifecycle management. It spans the full IC test lifecycle, from DFT insertion during design, through test pattern generation for manufacturing, to in-field monitoring during the operational life of the chip. Tessent is the de facto standard for automotive ICs requiring ISO 26262 compliance and for any high-reliability application where silicon quality and in-field safety are non-negotiable.

The platform covers every aspect of IC test and quality. Tessent Shell provides unified DFT insertion including scan chain stitching, test compression, and wrapper architecture for hierarchical design. Tessent TestKompress generates highly compressed ATPG patterns that minimize test time and ATE memory while maintaining fault coverage. Tessent MemoryBIST and Tessent LogicBIST embed self-test controllers for on-chip testing without external ATE. Tessent Diagnosis analyzes production test failures to identify root-cause defect locations, enabling yield learning feedback to the foundry.

For automotive IC teams, Tessent Safety provides the in-system test infrastructure that ISO 26262 requires for ASIL B through ASIL D functional safety, periodic LBIST and MBIST execution during vehicle operation to detect latent faults. Tessent Silicon Lifecycle Management extends this capability beyond manufacturing test into the operational life of the chip, monitoring aging, thermal stress, and degradation in the field.

GSAS Micro Systems provides Tessent licensing and technical support for semiconductor design and test teams across India, with expertise in DFT flow integration, automotive safety compliance, and production test optimization.
