In Platform Studio, I get the following synthesis error deep inside the plb_pci core. The PCI source code is encrypted, so there is not much I can do to debug.
"ERROR:Xst:2587 - Port < B > of instance <I_Fifo_near_full> has different type in definition <equality_cmpr>.
entity <equality_cmpr> with generics:
C_CMPR_WIDTH: from generic/parameter on instance : integer (-2147483648 to 2147483647) := 9
C_GATE_OUTPUT: from generic/parameter on instance : bool := false
ERROR:Xst - Unexpected error found while building hierarchy."
