The new platform provides an entirely new interactive and modernised software infrastructure for all OA-based Laker products, including the Laker Advanced Design Platform (ADP), Laker Custom Layout System, Laker Custom Digital Place and Route, as well as the new Laker Analog Prototyping tool. The platform increases OA performance, introduces next-generation layout technologies that are tuned for 28nm and 20nm design rules, and fully supports multi-vendor design flows with Interoperable process design kits (iPDK) and third-party tool integrations.
The new Analog Prototyping tool has been developed to provide early feedback on the impact of layout parasitics and other layout dependent effects (LDE), which can be particularly challenging to manage at the 20nm node. Its unique capabilities enable automated constraint generation, layout exploration, and rapid implementation in a single flow.
The Laker3 platform is built on a performance-driven infrastructure with pervasive multi-threading, new ultra-fast drawing capabilities, and 2-10X faster read/write operations compared the Si2 OpenAccess reference implementation. It also features an updated graphical user interface (GUI).
The design entry, custom layout, custom digital place and route, and analogue prototyping tools share the same binary executable creating a unified environment that enables passing of design intent between tools improving overall accuracy and user productivity.
A new DRC engine that addresses 20nm design rules is used by Laker automation tools and for rule-driven editing during layout. For layout editing with ‘sign-off’ rule decks, which is critical for 20nm designs, Laker uses the award-winning Mentor Calibre RealTime interactive DRC tool. In addition, beginning with this release, interoperable PyCells can now be used with all Laker automation features that previously supported only MCell parameterized devices .
The Laker Analog Prototyping tool is built directly into the Laker SDL flow to automate the process of analysing advanced process effects and generating constraints to guide circuit layout. This rapid prototyping flow results in a more predictable design cycle and improves productivity with less time wasted on post-layout design adjustments compared to conventional methods.
“Laker is the most widely used and broadly supported custom design solution with unmatched support for interoperable PDKs and multi-vendor tool flows,” said Dave Reed, senior director of marketing for custom IC design solutions at SpringSoft. “The new Laker3 platform builds on this foundation through the experience gained working with many customers worldwide and our continued investment in next-generation technologies. Collaboration with leading-edge companies working at 20nm was especially instrumental in driving the important new capabilities needed for advanced geometries.”
