Why does the SignalTap II Logic Analyzer Node Finder not display any signals?

Description

This problem can occur if you have different capitalization between the Project Navigator and the Node Finder. The hierarchy name are case sensitive and different case will represent different hierarchy path. If this is true, no matches are displayed in Nodes Found window when you list node in SignalTap™ II Logic Analyzer Node Finder.

Resolution

To avoid this problem, correct the mismatch in capitalization by re-selecting the top-level hierarchy in your Quartus® II project. To do this, perform the following steps:

1. Open the Settings dialog box from the Assignment menu
2. Select the General category
3. Click on ... to browse the list of modules
4. Select the correct top-level entity from the Select Entity dialog box.
5. Click OK to save your changes
6. Recompile your design

The Node Finder should now be able to find signals successfully.
