Error (170143): Final fitting attempt was unsuccessful Info (170236): Routing optimizations have been running for X hour(s)


Due to a problem in the Intel® Quartus® Prime Pro Edition software version 18.1 and earlier, you may see this fitter error  when compiling for the Intel® Stratix® 10 devices. This error may occur when enabling the Signal Tap Logic Analyzer is enabled.


This problem is fixed beginning with version 18.1 Update 1 of the Intel Quartus Prime Pro edition software.
