Lesson 10 - Comparing waveforms

---

The goals for this lesson are:

• Compare two simulations using the Comparison Wizard
• View comparison results and timing difference markers in the Wave window
• Use compare icons to jump to "previous" and "next" difference markers
• View comparison results in the List window
• Set an edge tolerance

Waveform Comparison computes timing differences between test signals and reference signals. In this exercise we're going to run and save the mixedHDL simulation, edit one of the source files, run the simulation again, and finally compare the two runs.

The general procedure for comparing waveforms has four main steps:

1. Selecting the simulations or datasets to compare


2. Specifying the signals or regions to compare


3. Running the comparison


4. Viewing the comparison results
