Taiwan EDA firm SpringSoft Inc. has expanded its Laker custom IC design platform with the introduction of Laker Custom Row Placer and Laker Custom Digital Router.

Laker Custom Row Placer uses proprietary automation techniques to achieve incremental selection and placement as well as internal iterations to pack the placement area. It utilizes stacking utilities for datapath-style placement. The row placer also assists routing with features for row snapping and overlap removal as well as diffusion sharing for area minimization.

Meanwhile, the Laker Custom Router is a hybrid router with both gridded and shape-based routing technologies. It allows off-grid routing to reach off-grid pins and uses shape-based routing to fix any design rule violations.

The router, SpringSoft added, supports 3D global route and features a congestion analysis map and display. It correlates with the Custom Row Placer to ensure routable placement. It provides utilities such as support for end-of-line spacing, min-edge/min-area, enclosure edge, and post-route optimization. It also allows a separate post-route DRC verification run.

SpringSoft said Laker Custom Row Placer and Laker Custom Digital Router are compatible with the Later Custom Layout Automation System and are compliant with the OpenAccess database.

"The changing nature of mixed-signal chipsgreater intermingling of digital with analog and much greater use of digital standard cells in mixed-signal blocks, smaller geometries, increased performance needs, and low-power constraintsrequires a more efficient and integrated approach to custom IC design," stated Duncan McDonald, director of product marketing for custom IC design solutions at SpringSoft. "These new tools build on the strong foundation of custom IC design technology in our Laker system and add very efficient automation for the digital portions of designs."

SpringSoft said pricing for a three-year time-based license starts at $35,000 per year for the Laker Custom Row Placer and $65,000 per year for the Laker Custom Digital Router.
