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.
