Design for Testability verification and validation are critical to ensuring that test structures are correctly implemented and capable of delivering the intended fault coverage. As semiconductor designs grow in complexity, robust DFT verification ensures that scan, BIST, and test access mechanisms operate as expected before silicon fabrication. DFT validation minimizes test escapes, reduces silicon debug effort, and accelerates time-to-production. Avecas provides comprehensive DFT Verification and Validation services to help organizations deliver test-ready and production-quality designs.
Our services ensure confidence in DFT implementation across the entire design lifecycle.
We define structured DFT verification plans aligned with design architecture, test strategies, and coverage goals. Our engineers identify verification scope, test scenarios, and validation checkpoints to ensure thorough assessment of DFT logic. Early planning ensures efficient and comprehensive verification execution.
Well-defined plans reduce verification gaps and rework.
Avecas verifies scan chains, scan controllers, compression logic, and test access mechanisms. We validate connectivity, controllability, and observability across all scan elements. This ensures that scan infrastructure is correctly integrated and ready for ATPG.
Accurate scan verification improves test effectiveness
We validate Memory BIST and Logic BIST implementations to ensure correct initialization, execution, and result reporting. Our engineers verify BIST controllers, repair logic, and diagnostic capabilities. This ensures reliable self-test functionality in silicon.
Robust BIST validation reduces post-silicon debug risk.
Avecas supports fault coverage analysis to evaluate test completeness and identify coverage gaps. We assist in analyzing stuck-at, transition, and path delay fault models. This ensures that test quality meets production and reliability requirements.
High coverage improves product quality and yield.
We perform final DFT readiness checks prior to tape-out. Our engineers validate test configurations, generate signoff reports, and ensure that DFT implementation aligns with manufacturing requirements. This provides confidence in production test readiness.
Comprehensive signoff enables smooth transition to manufacturing.
