Lights! Camera! Multi-Patterning! Take Two!

Debugging multi-patterning errors is hard without helpRemember learning your colors in kindergarten? Learning how to debug color assignment errors in multi-patterning can sometimes seem just as confusing. In Take Two of the Tech Talk videos on multi-patterning, David Abercrombie continues his discussion with Brian Bailey of Semiconductor Engineering about color assignment issues, and possible corrective actions.

More often than not, a color assignment error condition has multiple correct answers, or worse, multiple wrong answers. Designers can waste a lot of time “trying out” different coloring and formatting corrections. Understanding your options, and how to determine the optimal solution, can be challenging, but new tool functionality can provide more detailed debugging information to help designers make the best choice.

If you’d like to learn more about Calibre® Multi-Patterning functionality, and our patent-pending warning rings that help designers avoid creating new errors when correcting existing errors, check out the Calibre® Multi-Patterning datasheet, or read our white paper, Mastering the Magic of Multi-Patterning.
