The most commonly used approach to analyzing objects in an HDL design, is based on the well-known digital waveforms available with any commercial simulator today. Such a time domain representation of data with respect to time, allows verifying many parameters of a designed digital system, but it may not be efficient for applications such as image processing, digital filter design, embedded system design, and others. This white paper presents Plot, a new solution for a graph-based analysis of HDL objects, correlations between them, and a number of practical applications for it.
