The reality of DFT for large and complex SoCs has introduced new risk into design schedules. DFT teams end up in the critical path to tape out while waiting for portions of the design to be complete, ...

Some new design-for-test (DFT) technologies are difficult, expensive, or risky to implement but offer significant benefits. Other technologies are easy to implement but offer minor improvements. The ...

Cut test pattern count and DFT time with a hierarchical DFT methodology with pattern retargeting. Hierarchical DFT takes a “divide and conquers” approach, in which each core is isolated by wrapper ...
