Review routing usage reported in the Fitter Resource Usage Summary report.
Figure 14. Fitter Resource Usage Summary Report

Average interconnect usage reports the average amount of interconnect that is used, out of what is available on the device. Peak interconnect usage reports the largest amount of interconnect used in the most congested areas.

Designs with an average value below 50% typically do not have any problems with routing. Designs with an average between 50-65% may have difficulty routing. Designs with an average over 65% typically have difficulty meeting timing unless the RTL tolerates a highly utilized chip. Peak values at or above 90% are likely to have problems with timing closure; a 100% peak value indicates that all routing in an area of the device has been used, so there is a high possibility of degradation in timing performance.

The figure shows the Report Routing Utilization report.
