Hi,

Tested with Quartus 13 and 17.1, on both of them the issue is fixed and there is no such error.

B.T.W

I had to set to 8 "what is the number of channels controlled by the reconfig controller?" so ALTGX_RECONFIG instances will have reconfig_fromgxb[9..0] although I have only two channels (PCIe and Basic).

why ?

It would be much simpler to understand and connect if GX reconfig port would be a seperate ALT instance take care the all PHY channels and not spread between ALTGX instances.
