Scan Mapping, Expectation Versus Reality? It's Time to Grab All the Scan Cells!

1 Jul 2022 • 1 minute read

We all look for 100% perfection and want to turn our dreams (expectations) into reality as far as we can. Are you also looking for a magic wand to turn expectation into reality?

The story applies to DFT world too!! Design for Test (DFT) techniques comprehensively provide measures to test the manufactured device for quality and coverage. We expect 100% coverage and fault testing.

And the hard work for the design starts right from the beginning, but what if there is a glitch during the synthesis stage? You might encounter issues with the mapping of registers to scan flops during the synthesis stage. Does this mean you cannot reach the goal? Will you not be able to move forward further in the scan insertion process?

Well, we can't commit to the other things, but when it comes to the issue of mapping registers to scan cells, we can pitch in!!

Are you excited to explore the solution to ensure proper mapping of scan cells from the library?

There is a ONE-STOP solution for exploring the reasons for flops not mapped to the scan flops in the form of videos on "Why Are Sequential Elements Not Mapped to a Scan Flop?"; refer to the channel videos on https://support.cadence.com (Cadence login required).

This channel contains videos that explain why certain sequential cells are not mapped to the scan flops during scan insertion flow in Genus Synthesis Solution. The videos cover several scenarios and how to handle them.
