Abstract:

Layout patterns are identified as problematic when they have particular parameters required to exceed standard limits. The problematic layout patterns are associated with preferred design rules in a DRC-Plus deck. Layout data is scanned to generate match locations of any problematic layout patterns. The match locations are forwarded to a DRC engine that compares layout parameters of the match locations to corresponding preferred layout rules in the DRC-Plus deck. The DRC-Plus check results are used to modify the layout to improve manufacturability of the layout.
