For modern technology nodes, users often run DRC rule files with a very large number of checks. During visual debugging of results in a layout editor, the user will often have to turn off other design layers to understand an error. This is very inconvenient from a usage point of view. Another debug challenge is that the color used for results highlighting can sometimes be the same as the color used for the original layer presented in the layout editor. This requires an additional user step in the debugging flow to change the display color for each result. This application note describes an automated approach, using Calibre YieldServer and Calibre RVE with the new Check Text Override feature, to consistently set this per rule file without requiring any direct rule file editing.
This feature is built-in in 2015 versions of Calibre RVE.
