An easier way to deal with design rule waivers (video)

An easier way to deal with design rule waivers (video)

At advanced nodes, design rules are necessarily more complex and restrictive. Although most of the time you can find a way to live with them, sometimes it’s necessary to seek a waiver from the foundry for a particular design feature. This involves documenting the feature, the design rules in question and the conditions under which the rules are failing, and can be a real pain in the neck.

Wouldn’t it be nice to have a more automated way to document waiver requests? If you’re a Calibre user there is a way, although you might not yet be aware of it. To rectify that, Saunder Peng, Mentor Graphics’ TME for Calibre Interfaces, has created a short video explaining exactly how document, review, and share Calibre DRC errors and waivers between designers and foundries using the facilities of Calibre RVE.

Once you have approval from the foundry to waive specific checks on a particular part of your design, how do you make sure those violations no longer pop up in your verification runs and waste your time? That is explained in this video

More “How To” videos are available on the YouTube IC Nanometer channel. Do you have an idea for a Calibre How-to video? They take requests! Chime in on the Mentor Communities Discussion Board.
