Vivado Constraints - LOC constraint does not support ranges in Vivado

Description

Use of a range value is supported for LOC constraints in UCF. 
 

INST "<instance_name>" LOC = SLICE_X18Y65:SLICE_X18Y70;

 
But the equivalent XDC constraint produces an error in Vivado:
 
set_property LOC SLICE_X18Y65:SLICE_X18Y70 [get_cells {<instance_name>}]

ERROR: [Common 17-69] Command failed: 'SLICE_X18Y65:SLICE_X18Y70' is not a valid site name.

 

Solution

Use of a Range value is not supported for LOC constraints in Vivado. 

To constrain objects' locations in ranges, use Pblocks instead.
