An Optimal Path To DFT Automation


To keep up with time-to-market demands when SoCs keep increasing in size and complexity requires the adoption of better DFT flows and technologies. One of the most successful changes in design-for-test (DFT) flows in recent years has been the deployment of hierarchical DFT. Taking the divide-and-conquer approach delivers real savings in test time and cost, plus keeps DFT out of the critical pat... » read more

The Single Best DFT Move You Can Make


A proven method to simplify a complex problem is to break it into smaller chunks. In the case of today’s large, complex SoCs, this means using hierarchical methods to design the blocks, then combine the results at the top level. While this sounds obvious, it hasn’t always been practical or technologically feasible to perform some tasks, like DFT, at the block level and translate that work s... » read more
