Innoveda/Intusoft Agreement to Provide Circuit Simulation
for DxDesigner Product Suite

MARLBORO, Mass., July 23, 2001 - Innoveda, Inc. (Nasdaq: INOV), a leading provider of innovative software and services for the design of advanced electronic products, today announced an agreement in which Intusoft will provide circuit simulation capabilities for Innoveda's recently announced DxDesigner™ product suite. Intusoft, the San Pedro, California-based designer of circuit simulation and test software, will deliver proprietary algorithms and simulation technology for DxDesigner, scheduled to be released later this summer. The agreement expands upon the existing OEM relationship between the two companies.

DxDesigner redefines front-end design engineering through a process of "design definition" that combines four key process technologies: component information systems; design entry and sharing; simulation and planning; and enterprise connectivity within a single, comprehensive solution. This enables better communication among geographically dispersed engineering and manufacturing teams, resulting in more efficient component selection, less post-layout rework, fewer design defects, and shorter prototype-debugging cycles.

DxAnalog Module
According to Rick Almeida, Innoveda's vice president of marketing, Product Realization Group, "DxDesigner stresses the need for simulation and planning as one of the critical components in design definition. To meet the simulation requirements of analog and mixed-signal circuits, the DxAnalog™ module will incorporate Intusoft's interactive SPICE (Simulation Program with Integrated Circuit Emphasis) engine, as well as the IntuScope5 waveform analyzer, SPICE modeling program, and extensive model libraries. Together, these tools will enable Innoveda customers to run Monte Carlo, optimization, sweep, and fault analyses on analog and mixed-signal PCB and IC designs, as well as on multi-discipline systems."

Competitive Advantage
Larry Meares, Intusoft founder and president, said, "Circuit simulation has become increasingly important as manufacturers strive to narrow time between new product introductions while retaining quality and decreasing costs. The complexity of today's systems demands stringent simulation and verification testing that can only be met with the latest technology. Our expanded relationship will help deliver that capability to Innoveda's customers."

Technology Benefit
Almeida added, "Without simulation templates, designers must enter nominal values for the parameters of their circuit. Then, to see the effects of parameter tolerance variation, designers must change those parameters using a cumbersome, time-consuming, and often costly process. With DxDesigner, electrical engineers will be able to customize advanced circuit analyses that include measurements based on parametric variations for intra-component sensitivity, root summed square, extreme value, worst case, and Monte Carlo statistical simulations."

Keith Kasregis, Principal Engineer and Electronic Design Automation specialist at Siemens Building Technologies, Inc., agreed, stating, "The strengthening of the relationship between Innoveda and Intusoft, along with Innoveda's renewed commitment to the analog simulation marketplace, is good news for us at Siemens Building Technologies. The more capabilities Innoveda can build into their solutions, the more reliable our designs will be. The immediate inclusion of Intusoft's new simulation scripts, optimization, sweep, and fault analyses in DxDesigner are great first examples of that."

About Intusoft's Technology
The DxDesigner product suite will incorporate technology from Intusoft's latest release of its ICAP/4 software, including significant new functionality for running Monte Carlo, optimization, sweep, and fault analyses. These functions customize SPICE-based netlists for enhanced circuit analysis that goes well beyond the traditional SPICE boundaries of AC, DC, and transient analysis. The proprietary simulation templates used by these analyses employ interactive command language (ICL) scripts that tell a netlist which operations to perform. After a simulation is complete, designers can run additional scripts to view waveform functions such as phase margin, complex mathematical transformations, and group delay. By incorporating Intusoft technology in DxDesigner, designers will be able to automate the selection of component values to achieve their specified design objectives and help ensure manufacturing compliance early in the design cycle.
