Extremelly confused in Cyclone V Transceivers reconfiguration

So i return to this problem after some time.

Now i'm stay off in this point:

The project consist of these modules:

- Separate FPLL with it own PLL Reconfigurator IP.

- Transceiver in external PLL mode (i use 2 TX PLL's - TXPLL0=622.08 and TXPLL1=2488.32, bonding xN used).

- Base speed of transceiver is 622.08 (and 322.04 for FPLL respectively).

- Transceiver reconfiguration IP (number of channels same as number of channels in transceiver, MIF reconfiguration enabled).

What results i have:

For channels count from 1 to 6 compilation are successful.

For channels count from 7 to 8 compilation fails with errors:

Can anybody help me with it?
