How to debug non-texted shorts using Calibre RVE
In addition to the texted shorts that are caught as part of the extraction process, there are non-texted shorts generated during the comparison process. Non-texted shorts are actual connectivity issues that have been analyzed and found to be a short by the comparison process. Once all of the texted shorts have been corrected, users can begin debugging these comparison errors, which can sometimes be tricky to correct. In this video we will learn how to use Calibre RVE to quickly debug non-texted shorts. Overview: To help fix non-texted shorts, users can use Calibre RVE to see a visual representation of the layout and source netlists used in the LVS run, and debug LVS discrepancies by comparing the source and layout schematics side-by-side. These schematics are especially valuable to designers when schematics are not otherwise available for debug (e.g., Verilog).
