Sequence Extends EM And V-drop Analysis To Full-Custom Designs; Speedview-AMS To Offer New Power-Rail Analysis Capabilities

SANTA CLARA, Calif.—(BUSINESS WIRE)—Aug. 28, 2006— Combining its award-winning Columbus-AMS extraction engine with electromigration and voltage-drop components from its CoolTime dynamic voltage-drop product, Sequence Design has created Speedview-AMS, the latest in a series of new tools for power-rail analysis. Speedview-AMS enables designers to diagnose EM and V-drop issues in full-custom designs.

"Columbus-AMS with Speedview allows designers to extract and analyze power rails in existing LVS flows using an up-to-date, high-capacity viewer for analyzing electromigration and voltage-drop problems," said Dr. Rob Mathews, Sequence vice president of extraction products. "Unlike general-purpose viewers, Speedview directly assists in finding, visualizing, and deciding how to fix EM violations and voltage drop in a design."

Speedview-AMS Feature Summary

Speedview-AMS uses geometric and parasitic information directly from Columbus-AMS, overlaying analysis results from external simulation. Key features and benefits are:

-- Visualize and quickly isolate electromigration and voltage-drop problems using tailored, geometric displays of per-net parasitic and analysis data

-- Find every violation, and document how to fix it, using interactively controlled violations displays with search, annotation, and save functions

-- Diagnose voltage drop with an uncluttered, parasitic-only view showing complete parasitic and device properties

-- Visualize overall trends or fine details of analytic data using interactively controlled color maps of rail polygons

The Columbus extraction product family is part of Sequence's high-performance, low-power design lineup which also includes PowerTheater, CoolPower, CoolCheck, and CoolTime, providing RTL and full-chip power analysis and optimization tuned to the design challenges facing engineers at 90nm and below. Columbus-AMS is both a foundation for the company's RTL-to-silicon, power-aware design tools for SoCs and the industry's leading RLC parasitic extraction tool for high-performance digital and analog/mixed-signal designs.

Columbus-AMS is fully integrated with Cadence's Analog Design Environment, and operates with Calibre, Diva, and Assura LVS tools for total flow compatibility in a familiar and trusted environment. More than 100 Sequence customers have achieved successful, high-performance tapeouts using Columbus-AMS extraction. For more information:


Price for a one-year TBL is $91,500 for Columbus-AMS with Speedview-AMS EM/V-drop analysis. The package includes integration with Synopsys's HSIM-PWRA (Lexsim) simulator.

    I too find the article a little misleading in some parts. Though it does state the facts correctly later, in some places the words are misleading. The webpage of Cooltime says it is indeed a cell based Vdrop Analysis tool. But its usage in the article gives an impression to the reader that Vdrop capabilities have been borrowed from the Cooltime. Later in the article it's evident that this is not quite true since an external simulation is actually done for analysis.
    The hype about speedview is that there is now a viewing capability provided with extraction as has been the case with most other competing products in the AMS design space. Good job done by Sequence, being a small company.

    The headline was very catchy and seemed impressive. After reading many times over I could read the fine print which brought about more clarity about the exact features. I didn't find it particulary high class engineering.
    To be precise Speedview does not offer any Vdrop analysis per-se, but has been now able to overlay the voltage values at different points, on top of the existing layout.
    The voltage values come from an external simulation. Speedview reads these values which need to specified in its own format. Then it annotates them on the layout geometries. Except a convenience of display there is hardly any information addition made by Speedview.
    The role of Cooltime isn't really visible. Cooltime analyzes cell based designs only. The above feature of displaying Vdrop values has nothing to do with either cell base or full custom designs. There is no SPICE simulation done by either Columbus and Cooltime and is left to the user.
    The claims made in the article seem to be exaggerated, and I request them to be reworded. Please change the headline to "Sequence OVERLAYS result of Vdrop analysis in the layout viewer"
