Sequence Design Inc. has combined its Columbus-AMS, a parasitic-extraction engine for analogue/mixed-signal, memory and full-custom digital designs, with components borrowed from CoolTime, its Power Theater power-analysis suite, to create a new capability of diagnosing electromigration (EM) and voltage drop issues in full-custom designs.

The new Speedview-AMS lets designers extract and analyse power rails in existing layout-vs.-schematic flows with a high-capacity viewer for examining electromigration and voltage drop issues in detail, said Rob Mathews, vice president of extraction tools at Sequence.

"What you are seeing here is that we are taking some of our SoC-related technology to allow our full-custom customers to perform power rail analysis," Mathews said.

Sequence said Speedview-AMS takes geometric and parasitic information directly from Columbus-AMS and overlays analysis results from external simulation. Speedview directly assists in finding and addressing any uncovered EM or voltage drop issues, Mathews added.

Visualization edge
Among the tool's key benefits, Sequence said, is the ability to visualize and isolate EM and voltage drop problems using tailored, geometric displays of per-net parasitic and analysis data.

The Columbus-AMS with Speedview-AMS is priced at Rs.42.7 lakh ($91,500) for a one-year, time-based license. The package includes integration with Synopsys Inc.'s HSIM-PWRA simulator, the company said.
