The highest possible logical channel address assigned to a transceiver channel in a
Stratix IV device is the same whether the channel is a regular transceiver channel or a
PMA-only channel.
Total Number of Channels Option in the ALTGX_RECONFIG Instance
You can connect every dynamic reconfiguration controller in a design to either a
single ALTGX instance or to multiple ALTGX instances. Depending on the number of
channels within each of these ALTGX instances, you must set the total number of
channels controlled by the dynamic reconfiguration controller in the
ALTGX_RECONFIG MegaWizard Plug-In Manager. Based on this information, the
reconfig_fromgxb and logical_channel_address input ports vary in width.
Use the following steps to determine the number of channels:
1. Determine the highest logical channel address among all the transceiver instances
2. Round the logical channel address value to the next higher multiple of four.
3. Use this value to set the What is the number of channels controlled by the
