Fitter Logic and Routing Reports

The Fitter generates the following reports if you specify one or more logic or routing settings in the Settings dialog box.

Cascade Chains Report

Displays a table showing the number of cascade chains with a specified length in the design. This report appears only if the design includes cascade chains or if your design targets a MAX3000 or MAX7000 device for compilation.

Interconnect Usage Summary Report

Reports the name, usage ratio, and usage percentage for each routing resource used for routing purposes in the current design.

The specific content of this report depends on the device used in the design. It includes a subset of the following interconnect resources: differential I/O clocks, direct link Definition, dynamic phase alignment (DPA) Definition clocks, DQS I/O Definition buses and muxes, , global clock Definition, , interquad clock Definition, LAB clocks, local interconnects, LUT chain interconnect Definition, buffers, output enable signals, Programmable Interconnect Array (PIA) Definition buffers, and regional clock Definition used as routing resources.

LAB Logic Elements Report

Displays a bar chart showing the number of logic elements per LAB in the design.

LAB-wide Signals Report

Displays a bar chart that shows the number of LAB-wide signals used by the LABs in the design.

LAB Distinct Inputs Report

Displays a bar chart that shows the number of distinct inputs in the LAB. Distinct inputs are signals with unique sources that are routed into the LAB.
