Calibre RealTime

Calibre RealTime

On-Demand Calibre signoff verification. Calibre® RealTime enables on-demand Calibre signoff design rule checking (DRC) for custom and analog/mixed-signal design flows, improving both design speed and the quality of results by providing immediate feedback on design rule violations and recommended rule compliance.

Providing the same automated check capabilities available to digital design checking, Calibre RealTime makes it easier for custom IC designers to produce high-quality, high-performance designs at all nodes within today's tight production schedules.

The award-winning Calibre RealTime platform completely transforms the custom/analog layout-verification-simulation loop by bringing Calibre signoff verification into the design creation process.

Calibre RealTime In-Depth

Calibre RealTime delivers Calibre signoff DRC inside custom and analog/mixed-signal design flows. With its ability to perform all checks in Calibre DRC, including recommended rules, pattern matching, equation-based DRC, and double patterning, Calibre RealTime lets custom and analog designers correct and adjust their designs during the layout process using the same foundry-qualified rule decks used by batch Calibre.

Imagine-no more time-consuming layout-verification-simulation loops, and no more unwelcome, costly manufacturing issues after tapeout. By allowing designers to correct and optimize "on the fly" during the design process, Calibre RealTime lets them make needed layout changes while the design is still highly flexible, and without slowing down the design process. In short, Calibre RealTime lets the designers drive the design process, not their tools. And because it's Calibre, the results can be trusted.

Calibre RealTime offers dynamic signoff-quality DRC to custom and analog/mixed-signal designers through the OpenAccess runtime model.

How does it work? Calibre RealTime provides a tight integration between the Calibre physical verification platform and the custom IC design and layout system, based on the OpenAccess industry standard. When invoked from the design tool, Calibre RealTime provides direct calls to Calibre analysis engines running foundry-qualified Calibre rule decks. Now, no matter how many drawn layers a design contains, or how many checks there are per layer, or even how complex those checks are, custom design groups working at all nodes can get to DRC-clean quickly and with Calibre confidence.

  • Custom design environments
  • Employs in-memory checking to ensure best performance
  • Supports user-defined custom filters tied to layout interface
  • Complements existing built-in checkers

Supported Integrations

  • Springsoft Laker™ design environment (version OA 2010.8)
  • Calibre IC Station® (version v10).

Interactive Editing/Verification

Interactive editing and verification of custom/AMS layouts ensures DRC-clean designs in the shortest time possible.

Instant Feedback

Calibre RealTime provides instantaneous feedback on DRC violations during layout creation and editing, enabling quick and accurate correction of the most complex configurations.

Shorter Design Cycle

Calibre RealTime reduces overall design cycle time by eliminating separate, time-consuming verification iterations.

Design Optimization

With more time in the design cycle, designers can provide more design optimization during layout creation, resulting in better quality and higher performance.

Improved Productivity

With more time and information during the design creation process, designers can concentrate on providing the best design possible. No more tedious design rule interpretations, and no waiting around for verification runs to complete.

One Tool, One Interface

Calibre RealTime runs within the custom design tool as an integral part of design creation flow. With a built-in toolbar, Calibre invocation is just a click away.

Calibre Confidence

Because Calibre RealTime uses Calibre analysis engines and foundry-qualified rule decks, designers can have full confidence in the results.

OpenAccess

Using the OpenAccess run-time model enables Calibre RealTime integration with most custom design environments.
