edXact Improves Jivaro, Comanche Tools

Backend verification specialist edXact SA announced that Jivaro, its netlist reduction tool and Comanche, its IC interconnections analysis tool, are now based on a common proprietary parasitic database. This further boosts each tool’s performance and enables a seamless combination to explore, analyze or reduce huge RLCK parasitic networks.

edXact (Voiron, France) is a provider of innovative tools aiming at accelerating detailed simulations within existing semiconductor design flows, while maintaining accuracy. Version 4.2 of Jivaro and version 2.0 of Comanche will be demonstrated at the Design Automation Conference in Anaheim, California, June 9-12.

“During the past year, edXact has been improving its products offering by building a common platform, called TOTEM, which combines a proprietary mathematical data base and a large set of innovative, efficient and accurate reduction algorithms,” stated Mathias Silvant, edXact President. “The simplified database greatly enhances model order reduction performance and also facilitates the implementation of future new features, like incremental netlist reduction.”

Explore, analyze and reduce
Three products are now based on the new platform and database: the two flavors of edXact’s flagship netlist reduction tool – Jivaro HD for mixed-signal and digital design, and Jivaro A for analog and RF design – and Comanche, their companion analysis tool. Comanche helps detecting gross errors in the design’s interconnections, which are extracted as huge parasitic networks. “Comanche can be used before the netlist reduction tool. It can be used to judge if a full-flavoured simulation lasting several hours is useful by eliminating a number of recurring design problems”, comments Silvant.

New products features
The comprehensive software suite for IC nanometer design helps backend physical verification teams to reduce time to market by enabling and speeding up post layout simulation of huge RLCK extracted circuits, while keeping a very high accuracy.

Jivaro 4.2: improved memory usage and simpler control
JivaroHD is a parasitic reduction software for digital designs ; it deals with DSPF, SPEF and now Mentor’s CalibreView format files. Compared to previous versions, JivaroHD 4.2 brings the following additional features:

  • The ability to handle controlled sources
  • The ability to change net’s topologies before reduction
  • Improved and simpler control of the reduction process
  • An API for programmable integration into automated verification flows

Performance, memory usage and reduction rate have also been improved in order to handle very large nets (like power supply).

Jivaro A 4.2: new reduction algorithms
Jivaro A is a parasitic reduction tool dealing with Spice, HSpice, Eldo and Spectre format files. Compared to previous versions, Jivaro A 4.2:

  • Can handle interconnect parasitic networks with a large number of ports
  • Can now also reduce controlled sources
  • Handles directly parasitic extracted views of the Cadence CDBA database

The SALSA GUI option, giving access into Jivaro A and Jivaro HD from the Cadence environment, has been improved to allow pre- and post-processing tasks.

Comanche 2.0: additional parameter calculations and a new GUI
Comanche is an exploration and analysis tool dealing with DSPF and SPEF format files and calculating pin to pin parasitic impedance values. Gross impedance errors in turn pinpoint errors such as wrong vias that can easily be corrected before launching timely simulations. Compared to Comanche 1.0 which mainly calculated resistances, Comanche 2.0 also calculates capacitances, Elmore delays, and S/Y/Z parameters which can be output in Touchstone format. A GUI has also been added to set the options and inspect the results.
