In a Partial Reconfiguration design targeting 7 series SSI devices (7V2000T, 7V1140T, 7V870T & 7V580T), a reconfigurable pblock is not allowed to cross SLR boundaries.
Can I use SNAPPING_MODE to prevent placement of reconfigurable pblocks across SLR boundaries?
No, turning on SNAPPING_MODE will not generate a derived range which keeps the reconfigurable pblock in a single SLR.
The following DRC error will still occur:
To work around this issue, you will need to modify the reconfigurable pblock manually.
