DAC Report: SPICE and Fast SPICE Report this article as Inappropriate to us !!!Login to Reply

I visited some but not all SPICE and Fast SPICE suppliers at DAC in San Diego this year. Here's a quick trip report.

FineSim (SPICE) is parallel.
FIneSim PRO (Fast SPICE) is also parallel and unique. Has a feature to abstract transistors into gate-level black box for digital logic.
Strategy - throw your entire SPICE netlist into this simulator and use up lots of CPUs.
Lacking - customer success stories. PRO is still a flat simulator. No language integration.
Contact - KT Moore

AuSIM (Fast SPICE) is hierarchical and now parallel. Their booth theatre was a hoot and they attracted full audiences to collect cool rocket toys.
Strategy - simulate flat or hierarchical designs on one or multiple CPUs.
Lacking - first customer success story. Language integration.
Contact - Dino Caporossi

ADiT (Fast SPICE) is flat and integrated with language simulators for both digital and AMS. Maybe next year they will be parallel.
Eldo (SPICE) is mature.
Strategy - simulate analog transistors with Eldo, digital transistors with ADiT and use digital or AMS language for the rest of your SoC.
Lacking - no hierarchy, learning curve for AMS language.
Contact - Cyril Descleves

HSIM (Fast SPICE) is hierarchical and the marketing gorilla. New for this year is the XA engine which offers SPICE accuracy.
HSPICE (SPICE) - Mature.
Strategy - flat designs simulate in NanoSim, hierarchical designs in HSIM.
Lacking - parallel simulation, why offer both HSIM and NanoSim?
Contact - Mike Demler

UltraSim (Fast SPICE) - couldn't find it at DAC!
Spectre (SPICE) - mature.
Strategy - hierarchical simulator stand-alone or with AMS languages.
Lacking - recent customer success stories, not parallel yet.
Contact: ?

Xoomsys - Not a SPICE or Fast SPICE simulator but enables you to use a compute farm with existing SPICE simulators.
Strategy - put all those HSPICE licenses to work on long running jobs to improve run times.
Lacking - first customer success story.
Contact: Anjaneya Thakar

Summary - To tackle big transistor-level designs or long runs requires a circuit simulator to adopt some new techniques, like: Fast SPICE, hierarchy, multiple CPUs or mixed AMS languages. Most suppliers use one or two of these techniques. Synopsys, Cadence and Mentor are the most mature product choices.
