FlipChip PIO Flow: Assignment of Bumps fails, but why?

Hi there,

when I try to assign signal bumps (EDI 14.12) to my IO pins, I always get this error message:

**WARN: (ENCSP-6014):    I/O pin 'DATA_IN[82]' does not connect to placed Area I/O instance or hard macro and will be ignored for bump assignment. Most likely reason is:
1. The Area I/O instance or hard macro is not placed.
2. I/O pin does not connect to I/O instance or hard macro in Verilog netlist.
[...]
**WARN: (ENCSP-6011):    There is no I/O pin to assign.
*** End Bump Assignment (cpu=0:00:00.0, real=0:00:00.0, mem=1135.2M) ***

I checked both reasons:

1.) I checked properties of the IO cells, they all have status "PLACED"

2.) I assigned the IO pins within my vhdl code, thats why all the io cells got found even without loading an IO file. And also in the synthesized netlist, they are there

According to the SoC user guide, I did the following steps:

• init design
• load io file, load eco file
• load floorplan file
• placePIO
• ciopCreateBump
• assignBump

So what am I doing wrong here? Why aren't the bumps got assigned?
