The OptoDesigner Design Rule Checking (DRC) module provides powerful capabilities to verify PIC designs prior to sending mask data to foundries.
OptoDesigner supports several ways to automatically verify PIC designs:
The Design Rule Checking Module can perform an extensive number of additional checks on the final mask data in the GDS file, ranging from single-layer rules such as the minimum feature size to rules that apply to multiple mask layers.
DRC is a standard step in the design flow for electronic IC design. This is now becoming a common practice for PICs, where it is important for the DRC engine to process curvilinear shapes, in contrast to the traditional Manhattan patterns in electronics.
