I'm attempting to pinswap pins between parts of a multi-package heterogenous FPGA part. I can't get the back annotate function to work even though I believe I have set up the part properly to support cross-package pinswapping.
U55.F11 Swap Id: 7
U55.A4 Swap Id: 8
FPGA's Swap_Info: (S1+S2+S3+S4+S5+S6+S7+S8),(S9),(S10)
Swap File: PINSWAP U55 F11 A4
Using the backannotate function with the swap file above yields the following error:
"Cannot swap pins F11 and A4 of U55H because they are not located on the same device"
"Cannot swap pins F11 and A4 of U55G because they are not located on the same device"
CHANGEPIN seems to work cross-package but doesn't produce the same results as PINSWAP.
Any ideas on what might be going on?
