The Calibre Fundamentals: Writing DRC/LVS Rules" course will teach you to effectively write and maintain Calibre nmDRC and nmLVS rule decks for your semiconductor processes. In this class, you will extensively study the Standard Verification Rule Format (SVRF) language used in Calibre rule decks.
The lecture modules will guide you through the various concepts underlying state-of-the-art layout verification techniques and specific aspects of the Calibre toolset. Hands-on lab exercises will reinforce lecture topics and provide you with rule-writing experience under the guidance of our industry expert instructors.
- Completion of the Calibre nmDRC/nmLVS class is very highly recommended
- Thorough knowledge of IC layout techniques and procedures
- Experience with an IC layout editing tool
- Good understanding of SPICE netlists
- Familiarity with UNIX
- Good understanding of layout verification concepts and experience with layout verification tools
PRIMARY COURSE TOPICS
You Will Learn How To
- Write DRC rules that perform a full complement of layout dimensional checks
- Write specification statements to control DRC output
- Use Boolean and topological operators to derive new layer data
- Debug rule files
- Write polygon-directed and edge-directed checks
- Write basic and enhanced antenna rule checks
- Improve DRC run-time efficiency
- Write equation-based DRC rule checks
