To use the RPM_GRID system, set a property on any cell in the RPM set:
attribute RPM_GRID of ram0 : label is "GRID";
As long as at least one cell has the RPM_GRID property equal to GRID, the RPM_GRID coordinate system is used.
Although the RPM_GRID coordinates are absolute based on the target device, they define the relative placement of the elements of an RPM set.
During implementation, the RPM set can be placed at any suitable location on the device.
