The RPM_GRID coordinate values differ significantly from the coordinate values of the SLICEs on the FPGA. These coordinates:
- Are stored as RPM_X and RPM_Y properties on device sites in the Vivado tools.
- Can be queried using get_property.
The following example does the following:
- Gets the RPM coordinates from a selected SLICE.
- Uses join to output both the X and Y coordinates in the required
format.
join "X[get_property RPM_X [get_selected_objects]]Y[get_property RPM_Y [get_selected_objects]]" X25Y394
