Why are the signals in the Signal Tap Logic Analyzer which are actually connected displayed in red ?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition software version 18.1 and earlier, the signals in the Signal Tap Logic Analyzer may be displayed in red, even though they are actually connected to the internal nodes during compilation.

Workaround/Fix

To check whether the signals in the Signal Tap Logic Analyzer are correctly connected, go to the Compilation Report > Synthesis folder > In-System Debugging report. The actual connection column reports the real connection after compilation.

This problem is scheduled to be fixed in a future version of the Intel Quartus Prime Pro Edition software.
