Virtual Prototype Analysis

Virtual Prototype Analysis (VPA) is a structured methodology for system level signal integrity analysis.  VPA is part toolset, part process and part mindset.

Analysis stages include model development and validation, pre-route design space exploration, real-time post-route validation, system-level optimization and documentation.  Using VPA, systems designers can accelerate their design cycle, increase design performance, improve design reliability and improve control over design manufacturing costs.  VPA employs hundreds of thousands of pre- and post-route signal integrity simulations to develop system level design trends relating to key performance parameters (eye height, eye margin, compliance margin, etc.) to key system design criteria (backplane length, connector pin, SerDes EQ setting, etc.). VPA allows large simulation databases to be interactively mined for a wide variety of information, providing deep insight into how key design decisions affect overall system performance.

From Our Customers:

"This is the second generation of Virtex technology where we have collaborated with SiSoft to develop and correlate IBIS-AMI models to reference simulations and hardware.  The combination of these IBIS-AMI models and SiSoft’s QCD provides customers with accurate simulation results at speeds more than 100 to 1000 times faster than traditional simulation methodologies, allowing customers to quickly optimize their designs for cost, reliability and performance.”
