Expanding the scope of Mixed-Signal Verification with Symphony Mixed-Signal Platform

The number of mixed-signal interactions and the complexity of the feedback loops on ICs is increasing which makes verifying them a difficult and error prone task. Verification teams have traditionally used mixed signal simulations with relaxed accuracy settings for the analog portion as part of their functional verification flows at the top level and subsystem level to achieve good performance with the goal to catch primarily errors in A/D (analog/digital) connectivity and interfaces. Many errors that result from realistic analog block behavior which can affect digital blocks through A/D feedback go undetected in relaxed accuracy simulations thereby causing chip failures. Symphony Mixed-Signal Platform delivers the accuracy needed with fast mixed-signal simulation performance to be able to catch the errors resulting from the realistic behavior of analog blocks and A/D feedback.
