When you run report_utilization in the Tcl Console without the
-name option, the text report includes prohibited sites and fixed
cells on each line.
Prohibited sites affect how the tool calculates available resources, using the following formula:
Available resources =
total resources – prohibited resources
A cell is considered fixed when it has the IS_LOC_FIXED property set to 1. This property is automatically applied
when you assign a LOC constraint to the cell.
