You can re-use the .mif generated for a transceiver channel on one side of the device
for a transceiver channel on the other side of the device, only if the input reference
clock frequencies and order of the pll_inclk_rx_cruclk[] ports in the ALTGX
instances on both sides are identical.
In addition to the input reference clock requirements when re-using a .mif, refer to
“Guidelines for logical_tx_pll_sel and logical_tx_pll_sel_en Ports” on page 5–58
additional ways to re-use a .mif.
Guidelines for logical_tx_pll_sel and logical_tx_pll_sel_en Ports
This section describes when to enable the logical_tx_pll_sel and
logical_tx_pll_sel_en ports and how to use them in the following dynamic
reconfiguration modes:
