Calibre YieldEnhancer

Calibre® YieldEnhancer offers an automated approach to layout enhancements that will improve yield. It addresses the issue of area with a core philosophy to take advantage of any white space. This method improves yield without sacrificing area. To balance performance, YieldEnhancer offers both a net-aware capability and back annotation to the design database. To determine the impact on yield, YieldEnhancer works with Calibre YieldAnalyzer to measure the impact of the layout modification.

To reduce those hot spots in a practical and efficient way, Calibre YieldEnhancer provides you with automated layout enhancements that include built-in functions optimized to maximize coverage and minimize run times. Calibre YieldEnhancer performs multi-layer operations that support multiple configurations that maximize the coverage and minimize jogs. Configurations include 1) single via additions, 2) replacement of a single via with two symmetrically placed vias, 3) edge modifications based on multi-layer checks, such as enclosure and extensions rules, and 4) single layer grow operations. Layout modifications remain DRC clean while taking advantage of as much white space as possible. To ensure you maintain design performance, Calibre YieldEnhancer also offers both a net-aware capability and back annotation to the design database.

All modifications are fully back-annotated to GDSII, OASIS®, LEF/DEF, OpenAccess™ and Milky Way™ design databases.
