Visualize and Interpret Parallel Link Project Analysis Results

Visualize and interpret the network characterization and statistical and time domain analysis results

Using the Parallel Link Designer app, you can analyze the results of network characterization and statistical and time domain analysis. The app reports various metrics and visualizations including the eye diagrams, bathtubs, and contours to provide insight into your design. You can also perform waveform and timing analysis.

You can also use data mining and advanced visualization techniques to narrow down the large simulation data to focus on the area of your interest.

Featured Examples

DDRx Timing and Waveform Mask Analysis

Use the Parallel Link Designer app to perform timing analysis for the DDR (Double Data Rate) family of memory interface protocols. You can use either Setup and Hold margins or by waveform eye-diagram compliance masks to perform the timing analysis. The DDR Memory Down (DDR4_MD) example kit uses both timing and waveform mask analysis. Specifically for DDR4 systems, timing analysis is performed on clock-address/command interface, and waveform compliance masks are applied to strobe-data(DQS-DQ) interface. Other DDR types may use only timing analysis, or only waveform mask analysis or a blend depending on individual standards.
