ALT2GXB in 3 modes

hi all.

I have some problems with reconfiguration of ALT2GXB in my project.

i have SFP connector and Stratix II GX transceiver.

i can use SFP module with 3 speeds: STM-4(622.08 MGz), STM-16(2,5 GGz), GIGE(1,25 GGz). i have to switch mode of my transceiver.

i make follow scheme: 1 transceiver, 1 alt2gxb_reconfig, 3 ROM blocks for every mode and configuration logic. via external jampers i can switch mode, control logic choose 1 ROM from 3 blocks. on rise edge of write_all signal reconfiguration starts.

Are errors in this scheme?

but main problem is - i don't know how generate MIF-files for EACH mode.

Does anyone know?

i need some help.
