2 Agenda Sign-off DRCs in Custom Design An Engineering View of Integration Video demo Summary

3 Growth in Signoff DRC Rules and Complexity Well M1 only M2 M10 only Other Normalized Number of Checks nm 40nm 28nm Technology Node Twice as many checks at 28nm Complexity outpacing designer s ability to memorize! Mentor Graphics Corp.

4 Physical Verification Trends: Increasing DRC Complexity Double Patterning Pattern Match Pattern Match On-grid checks On-grid checks Pitch checks Pitch checks Pitch checks Litho checks Litho checks Litho checks Multi-dimension checks Multi-dimension checks Multi-dimension checks Multi-dimension checks Multi-dimension checks nm nm nm /32 nm /16 nm Mentor Graphics Corp.

5 Physical Verification in Laker Laker rule-driven layout M1.1 M1.2 Dynamic DRC guidance Support advanced production processes Not sign-off Third-party sign-off integrations Run and review a designated window, cell, or chip Sign-off deck, bleeding-edge rules

6 Imagine Sign-off Driven Layout What if we could offer Calibre DRCs in real time? Off-grid enclosure Pattern matching Double patterning Imagine real time 20nm sign-off DRCs while you edit

7 Benefits of Real Time Integration Identify sign-off DRCs upstream while change is relatively inexpensive Reduce lengthy iterative loops Fixes stay fixed, dramatically reducing DRC review time Instant what-if analysis for recommended rules

8 How do you get two competitors. I know the rules and how to check DRCs! I know what s changed and how to fix them!..to work together?

9 The Right Ingredients Calibre is the gold standard for DRCs SpringSoft has experience with partner OA-RTM integration Mentor has experience integrating Calibre engine in Olympus-SOC A perfect marriage?

10 3 rd -party Integration Challenges Interactive speed requires direct access to the in-memory data of the design tool In-memory API s require binary compatibility Compilers and Linkers, including version OA enables tight 3 rd -party integrations Published API Tiered database, +plug-ins, +run-time model Supported by many custom design tools OA integration still requires cooperation, but is manageable Mentor Graphics Corp.

11 Laker Integration Tcl package & shared lib Laker Calibre Client Calibre Server OA Memory Model OA Database Software from 2 vendors, working from a single memory model Mentor Graphics Corp.

12 Calibre RealTime: Custom Design 90nm ~ 1100 checks & 5900 shapes 0.2 sec 28nm: 2805 checks & 6649 shapes 0.3 sec Standard sec RealTime 0.2 sec Mentor Graphics Corp.

13 Laker Integration: Key Technologies OA Observers Shape Observer: Triggered any time a shape is added, deleted, modified, or moved Instance Observer: Triggered any time an instance of a cell is added, deleted, or moved Laker s Tcl APIs Used for tool-access APIs Registering custom commands Loading C++ shared libraries for performance Used Tcl package mechanism to load shared library Requires platform and compiler compatibility Used existing APIs for 90% of the integration Mentor Graphics Corp.

14 Laker Integration: Challenges and Solutions Provided toolbar for error navigation SpringSoft provided hooks to install a toolbar Layer mapping is not in OA memory model Used Tcl APIs to access layer mapping Visible and edited layer checks Used Tcl APIs to access information Software distribution RealTime code distributed with Calibre product Loaded into Laker through startup script Cooperative development eased tight integration Mentor Graphics Corp.

15 Selecting Rules Dynamically select checks based on user s activity in the design tool Mentor Graphics Corp.

17 An Open Eco-System Two competitors who understand what customers want, can work together to create tools users want in an open environment Increasingly, users are recognizing the value of interoperability
