Laker Custom IC Design Tools Feature Built-in DFM Capabilities

Silicon Canvas, developer of the Laker suite of high-performance tools for custom IC design, announced the release of the first design for manufacturability (DFM)-compliant technology files offering built-in DFM targeting TSMC advanced process technologies.

In a new use model pioneered in Silicon Canvas’ Laker custom IC design tools, when design for manufacturing and “recommended” rules are included in the Laker tech files, the user can choose from a number of recommended rule sets, and Laker’s built-in DFM features will automatically generate – or guide the user to generate – layout incorporating a more manufacturable and DFM-compliant configuration. These built-in Laker DFM features require no scripting and support advanced design requirements such as multiple rule sets; conditional rules; recommended rules; discrete gate spacing; minimum area rules; routing jog avoidance; via-doubling; and more. DFM rules are supported in Laker’s patented M-cell device generator and rule-driven layout flows.

In advanced processes, design rule documents may contain hundreds of layout design rules, including alternative recommended and DFM rules. These rules define a set of best practices for physical designs intended to avoid yield-limiting layout and reduce the number of DFM “hot-spots” found in post-layout simulation. It is a daunting task for a designer to remember even the basic minimum design rules (typically flagged by DRC tools) let alone multiple alternative rule sets. Laker’s built-in DFM features make implementing recommended and/or DFM rules both practical and easy.

“Silicon Canvas’ Laker platform makes it simpler for designers to implement DFM recommended rules with DFM tech files,” said Kuo Wu, deputy director of design service marketing at TSMC. “The ability to create DFM-compliant layout automatically from the start will reduce the time required to achieve DFM compliance at the end of the design flow.”

“Silicon Canvas is pleased to collaborate with the world’s largest foundry in its DFM compliance initiative to reach this technology and design milestone,” said Dr. Hau-Yung Chen, President of Silicon Canvas. “TSMC and many of our mutual customers have helped to define the original set of built-in DFM features and we look forward to working with them in the future to provide even more advanced design-side DFM automation.”
