LUTRAM stress test underutilization

[tarik-ibrahimovic]

Already discussed here running 8.StressTest/LUTRAM_Stress_test causes the router to fail at approximately 10% CPE utilization. Recognizing the challenge posed by the wide output multiplexer routing, I modified the test to focus solely on memory capacity—using the 8.StressTest/LUTRAM_adjusted_stress_test, where outputs are condensed to a single bit. Even with this adjustment, we haven't exceeded 58% utilization.

I'm trying to determine which aspect of the design is causing the constriction, but I'm struggling to find the crucial information. Specifically, I have two questions regarding the debugging process:

1. How to extract information about the routing fails tracing it to the source from messages such as: FATAL ERROR: 106 not routed! or CPE_OUTMUX congestion at Component 333 with 353
2. How to view cdf files? Like in this presentation.
