Software couples with Simulink for RF design.

Press Release Summary:

GoldenGate RFIC Simulator interfaces with Simulink® from The Mathworks to couple system-level and transistor-level simulation for RF design. Using Simulink, RF Blockset, and Model-Based Design, engineers can validate executable model of entire communications system against requirements. RFIC designers can reuse same model as test environment, enabling users to verify that transistor-level design will behave correctly in target system.

Xpedion Design Systems Introduces Integration with Simulink® from the MathWorks

Milpitas, CA (USA) - February 13, 2006 - Xpedion Design Systems, Inc., the leading RFIC simulation company, today announced an interface to Simulink® from The MathWorks to couple system-level and transistor-level simulation for RF design. Designers will be able to use Simulink® in conjunction with Xpedion's GoldenGate RFIC Simulator to bridge the gap between system-level specifications and transistor-level performance.

"Using Simulink, RF Blockset, and Model-Based Design, system engineers can validate an executable model of an entire communications system against requirements," says Colin Warwick, RF product manager at The MathWorks. "With this new link, RFIC designers can reuse that same model as a test environment. This lets users verify that a transistor-level design will behave correctly in the target system."

The current design methodology for advanced RFIC development starts with architectural tradeoffs made in Simulink. Once the specifications are developed, they are passed on to the RF designer, who is responsible to meet those specifications at the transistor level. Through the new design flow, designers can use the actual modulated signal, generated using Simulink, in GoldenGate, thus ensuring specifications are met.

Furthermore, Xpedion is currently developing a co-simulation interface. This interface lets the system-level designer use a live co-simulation link to verify a transistor-level design in GoldenGate by executing a system-level model in Simulink. The benefits include thorough wireless verification and significant time-to-market advantages. This unique flow is available for demonstration upon request.

"Simulink is rapidly becoming the standard for complex RF system design," said Pete Johnson, director of marketing at Xpedion. "Xpedion looks forward to continued collaboration with The MathWorks to continue to solve our customers' design needs."
