LG adopts IC validator, compiler from Synopsys

Synopsys Inc. has revealed that LG Electronics Inc. has adopted its physical verification applications tool as part of their design implementation flow for ARM processors. LG has integrated IC Validator's in-design technology with Synopsys' IC Compiler place-and-route solution that according to the company sped up manufacturing compliance for LG by two weeks.

With feature geometries shrinking, the number and complexity of DRC needed to achieve manufacturing compliance has grown exponentially. This has rendered the traditional physical verification approach, which relies on modifications to design after the GDSII has been generated, disadvantageous. The traditional approach can create multiple discover-then-fix iterations and can lead to suboptimal results. Examples are metal-fill insertion and design-rule checking, which today are universally mandated manufacturability compliance steps.

The traditional approach would require physical designers to stream out the timing-closed, post-fill design for signoff validation and then stream it back in to fix any errors, setting the stage for multiple iterations. The same concerns are also applicable to the traditional approach to generalized design rule checking after the design has been completed, potentially leading to late-stage surprises and ensuing expensive iterations that can significantly impact tape-out schedules.

In-design physical verification with IC Validator addresses these manufacturability challenges within the IC Compiler environment. The well-integrated flow enables an optimised metal-fill flow that is not only timing aware with sign-off quality, but also avoids expensive and error prone stream-outs and stream-ins. For design rule checking, the in-design flow uses foundry-qualified rule decks to flag errors in the layout and also drive automated repair, potentially saving days compared to the traditional approach of post-design validation and subsequent manual repairs.
