Part 1 of this series discusses the problems with at-speed testing, and the various defect models and manufacturing test techniques. This part will tackle at-speed timing closure rules and at-speed coverage. It also looks into the at-speed coverage estimation and diagnosis of SpyGlass-DFT DSM.

The SpyGlass-DFT DSM product provides timing closure analysis and RTL testability for deep subµm (DSM) defects associated with at-speed testing. It is touted to provide accurate RTL fault coverage estimation for transition delay testing, together with diagnostics for low fault coverage, early in the design flow.
