Connecting the ALTGX and ALTGX_RECONFIG Instances
There are two ways to connect the ALTGX_RECONFIG instance to the ALTGX
instance in your design:
■
■
In the dynamic reconfiguration interface, you must connect the reconfig_fromgxb
and reconfig_togxb signals between the ALTGX_RECONFIG instance and the
ALTGX instance to successfully complete the dynamic reconfiguration process. Make
the following connections:
■

Single dynamic reconfiguration controller—You can use a single
ALTGX_RECONFIG instance to control all the ALTGX instances in your design.

controller in a design.
Multiple dynamic reconfiguration controllers—Your design can have multiple
ALTGX_RECONFIG instances but you can use only one ALTGX_RECONFIG
instance per transceiver block, as shown in
Connect the reconfig_fromgxb input port of the ALTGX_RECONFIG instance to
the reconfig_fromgxb output ports of all the ALTGX instances controlled by the
ALTGX_RECONFIG instance.
Connect the reconfig_fromgxb port of the ALTGX instance whose starting channel
number is 0, to the lowest significant bit of the reconfig_fromgxb input port of the
ALTGX_RECONFIG instance.
Connect the reconfig_fromgxb port of the ALTGX instance with the next highest
starting channel number to the following bits of the reconfig_fromgxb of the
ALTGX_RECONFIG instance, and so on.
Connect the same reconfig_togxb ports of all the ALTGX instances controlled by
the ALTGX_RECONFIG instance to the reconfig_togxb output port of the
ALTGX_RECONFIG instance. The reconfig_togxb output port is fixed to 4 bits.
