After route_design, with the in-memory design still open, I execute PR_VERIFY to compare the Static_BB DCP (from after update_design -black_box) and the new routed configuration DCP that had just been written out:
pr_verify clk_wrap_postroute_bb.dcp clk_wrap_postroute_rm2.dcp
It fails with the following error:
ERROR: [Constraints 18-892] HDPRVerify-09: Mismatched Partition-Pin-Location found. There is a difference at interface net clk_wiz_0_exdes_inst/COUNT_OBUF connected to pin clk_wiz_0_exdes_inst/COUNT_OBUF.
Both design check points must have the same location for the equivalent Partition-Pins.
If I close the in-memory design, then run the exact same pr_verify command (which uses the same DCPs), it passes.
