Analogy Hits Another Milestone in Its TheHDL Roll-Out; Second Generation Prototype in Beta-Test

Business Wire, March 15, 1999

BEAVERTON, Ore.--(BUSINESS WIRE)--March 15, 1999--Analogy, Inc., (Nasdaq:ANLG) the world leader in mixed-signal and mixed-technology simulation, today announced that it has hit yet another milestone in the delivery of its mixed-signal open simulation environment outlined in its TheHDL(TM) strategy announced in December 1998.

The milestone is the on-schedule delivery of a second-generation prototype single kernel, language-independent mixed-signal simulation engine for Beta-Testing to assigned members of the Composite CAD Program, originated by the Defense Advanced Research Projects Agency (DARPA).

The new simulation engine was recently demonstrated at Analogy's Beaverton, Oregon headquarters to members of the Composite CAD Beta-Test Program, all of whom were provided with copies for immediate use in the design and research projects within the Program.

"Our partners and customers from the DARPA Composite CAD Program are extremely excited about the capabilities of our new simulation engine which includes a performance evaluation as part of the demonstration," said Doug Lundin, Vice President of Marketing at Analogy. "We see their continuing commitment as a confirmation of our TheHDL strategy."

This second-generation prototype is based on the final draft of the VHDL-AMS Language Reference Manual (LRM) which has remained unchanged since May 1998. It provides the DARPA Composite CAD Program members an early insight into a validated top-down design and simulation environment for mixed-signal and mixed-technology designs based on the forthcoming VHDL-AMS IEEE 1076.1 standard. The implementation of VHDL-AMS, however, is only the first step towards the language independent single kernel within Analogy's TheHDL environment.

Analogy's TheHDL vision is for a mixed-signal simulation environment with a single kernel simulation engine at its core encapsulated within an open architecture that is language aware and capable of supporting multiple hardware description languages (HDLs) such as VHDL-AMS, Verilog-AMS, VHDL, Verilog and MAST and model libraries.

By using a single kernel simulation engine rather than utilizing an array of simulation engines loosely linked via backplane or co-simulation technology, the TheHDL environment will be able to efficiently solve both analog and digital parts of a design. The simulation engine keeps them fully synchronized using Analogy's patented Calaveras(R) algorithm in much the same way that the Saber(R) simulator does today. The kernel of the TheHDL simulation environment is encapsulated within an open architecture, the specifications for which will be published by Analogy.

"An open architecture is critical to the adoption of a new mixed-signal simulation environment of this nature. It helps maintain the legacy investments made by customers as well as significantly improving functionality through the active involvement of university research and specialist third party companies," continues Doug Lundin. "We firmly believe that, in a standards oriented market, being open will help the market grow larger and faster."
