The following section describes the clocking requirements to re-use .mifs.
The .mif contains information about the input clock multiplexer settings and the
functional blocks that you selected during the ALTGX MegaWizard Plug-In Manager
instantiation. You can use a .mif to dynamically reconfigure any of the other
transceiver channels in the device as long as the order of the clock inputs is consistent.
For example, assume that a .mif is generated for a transceiver channel in transceiver
block 0 and the input clock source is connected to the pll_inclk_rx_cruclk[0] port.
When you use the generated .mif for a channel in other transceiver blocks (for
example, transceiver block 1), the same clock source must be connected to the
pll_inclk_rx_cruclk[0] port.
