AVGT development board PCIe and SFP pin assignment

To lihaiquan,

I'l having a similar problem: after assigning some output pins I get the error:

Error (12857): HIP reset pin "i_pcie_perst" is locked to "PIN_BD35", which is not legal.

The pins that I assigned are output signals which goes to the transceiver, and are placed in:

set_location_assignment PIN_W41 -to o_serial_data_GBT[0]

set_location_assignment PIN_U41 -to o_serial_data_GBT[1]

set_location_assignment PIN_R41 -to o_serial_data_GBT[2]

set_location_assignment PIN_L41 -to o_serial_data_GBT[3]

set_location_assignment PIN_N41 -to o_serial_data_GBT[4]

set_location_assignment PIN_J41 -to o_serial_data_GBT[5]

As you can see they are quite far from PIN_DB35, which is the one giving problems. The funny thing is that if I don't assign any pin to o_serial_data_GBT then the error goes away.

Did you still remember what you had to do to solve the problem?

Thanks in advance.
