Silicon Canvas adds interactive IC layout

After finding some market acceptance for Laker, its automated full-custom editor, Silicon Canvas Inc. has introduced a feature that gives users more control over the full-custom tool. Laker 3.1 is also the first connectivity-driven version of the tool, the startup said.

"Quality is the most important thing in full-custom design," said Hau-Yung Chen, president of Silicon Canvas. "The key is the control of automation" and Release 3.1 provides that control, Chen said. For example, it allows a user to guide the router manually, he added.

Since its founding in January 2001, Silicon Canvas has installed more than 160 Laker seats at locations in Taiwan, China, and the U.S. The company claims that Laker has led to some 400 tapeouts. As a "smart editor" that understands design rules, Laker is said to provide the quality of full-custom "polygon" editors, while supplying more automation than existing solutions.

The latest release lets users explore different layout topologies and manually modify a layout until it meets the requirements. Laker still automatically performs much of what was formerly a manual process, resulting in two- to six-fold productivity gains, according to the company.

Rules-driven generator

Laker 3.1 is also connectivity-driven, meaning it can be controlled from netlists or schematics. While other connectivity-driven solutions use prebuilt parameterized-cell approaches, Laker 3.1 provides the rules-driven Magic Cell device generator - an approach that can create devices on the fly.

The new release also adds a hierarchical net tracer and a short locator to help users better understand physical designs. Chen said Silicon Canvas is working to ensure that Laker 3.1 works within third-party tool environments by providing compatibility with both the OpenAccess and Milkyway databases.

Other Laker capabilities include stick diagrams and cell templates for placement exploration, a controllable shape-based router, flight lines to facilitate routing, an engineering change order capability, and design rule checking, electrical rule checking and layout versus schematic functions.

Laker 3.1 is available now starting at $35,000 per year for a three-year subscription for new users.
