SANTA CLARA, Calif. – Jan. 29, 2001 - Innoveda, Inc., a leading provider of innovative software and services for the design of advanced electronic products, today announced and demonstrated XTK™ with SPICE co-simulation, which enables analysis of crosstalk between connectors and packages on printed circuit boards. Innoveda also rolled out the latest version of the ePlanner™ tool that now enables designers to analyze PCB schematics from CadenceĀ® Design Systems, Inc.'s Concept-HDL™ tool. The enhanced XTK and ePlanner tools will be exhibited at Innoveda's booth (#515) at the DesignCon2001 show, Jan. 29-31 in Santa Clara, Calif.

Customers using XTK with SPICE co-simulation now can extend the crosstalk analysis available at the board level to include crosstalk inside of dense IC packages and connectors. This enables a more accurate analysis and the ability for customers to catch design problems earlier in the design cycle, rather than downstream where they are more costly to fix. XTK supports the Berkeley Standard SPICE model."XTK now goes heads above the competition because it uniquely combines the high speed of its transmission line algorithm with the benefits of SPICE co-simulation," said Rick Almeida, vice president of marketing for Innoveda's Product Realization group. "Since XTK is not SPICE-based, it is very efficient and very fast. Customers can actually use a SPICE-based model for drivers, connectors or packages, enabling XTK to perform die-to-die simulation."

XTK Defined

XTK is a signal integrity analysis and crosstalk tool kit that provides a powerful suite of tools designed to help solve signal integrity problems on single printed circuit boards, multi-board systems, and MCMs. XTK is used both for pre- and post-layout analysis. As part of Innoveda's ePlanner tool suite, XTK helps establish and drive rules forward into layout based on electrical constraints. As a post-route sign-off tool, XTK imports data from all popular layout systems and exhaustively simulates all signals, verifying that electrical constraints have been met.

XTK consists of two components: a 2.5D Field Solver that computes the inductive and capacitive coupling matrices needed for crosstalk and transmission line simulation based on PCB geometry and materials, and conductor paths; and a network simulator that uses a proprietary algorithm – 10 to 100 times faster than SPICE-based algorithms – to simulate the results of coupled transmission line effects on digital signals.

ePlanner Extends Choices

Innoveda also is announcing the latest version of ePlanner, its pre-placement or pre-layout PCB analysis tool. ePlanner now enables designers to analyze PCB schematics from three different source tools: Innoveda's ViewDraw™, Mentor Graphics™ Corp.'s Design Architect, and Cadence's Concept-HDL tools. This new functionality enables designers to select the planning environment of their choice. Unlike Cadence's SPECCTRAQuest™ and Mentor's Interconnect Synthesis (ICX™) that are focused on their own PCB design systems, Innoveda's ePlanner uses an open architecture supporting schematic data from many popular schematic capture tools.

ePlanner enables designers to do signal integrity and crosstalk analysis of a PCB design before layout, routing or fabrication. It uses XTK as the analysis engine. Designers can use XTK early in the design cycle, when it's easier, faster and less expensive to fix design problems.
