Coupling Analysis
Another major enemy of working designs is signal coupling. OrCAD X Presto PCB Editor addresses this concern as well
through simulation. To run this analysis, do the following:
1. Go to View > Panels > Analysis Workflows.
2. From the drop down within the Analysis Workflows panel select Coupling Workflow.
3. Under Analysis Modes, Choose Net Based, then click Select Nets
4. Add all nets to the right column for analysis, then click Apply and OK.
5. As before, you can Set Up Analysis Options and check any options that interest you.
6. After that, click Start Analysis. The software will perform its analysis, then generate results in visual form as an option
and tabular form through View Coupling Visions and View Coupling Tables, respectively.
You would check the analysis results then save them as needed.
As an example, you would have certain criteria that need to be met in order to know whether the results above are suitable.
