Abstract

Techniques are described that target extending usability ofexiting scan-based DFT approaches for activities beyond ICcomponent testing. In particular, the need for applyingDFT to improve product Time-to-Market is described andjustified. This need is evident from observations that aSystem on a Chip (SoC) design poses serious designverification challenges that may impact overall productsuccess in ways that can not be compensated for byimproving product quality. DFT features are described thatthat bring system-level diagnostics tools, such as the systemLogic Analyzer and the Service Processor, to the IC level inorder to facilitate post-silicon debug and verification.Finally, it is pointed out that much work remains to be doneby existing EDA companies (or new entrepreneurialcompanies) to provide new tools that integrate the newDFT features into the SoC synthesis flow.
