Section 1.1. New Features and Enhancements in the Intel® Quartus® Prime Pro Edition Software Version 19.1 Software and Device Support Release Notes says “Added Global Router Congestion Reports to show which nets contribute to routing congestions or no-routes.” But the correct report name is Global Router Wire Utilization.
The report can be accessed in Compilation Report > Fitter > Route Stage > Global Route. This feature is available in Intel® Stratix® 10 devices and Intel Agilex® devices.
