To connect the reconfig_fromgxb port between the
ALTGX_RECONFIG instance and multiple ALTGX instances, follow
these rules:
■
■
The Quartus II Fitter produces an error if the dynamic
reconfiguration option is enabled in the ALTGX instance but the
reconfig_fromgxb and reconfig_togxb ports are not
connected to the ALTGX_RECONFIG instance.

ALTGX_RECONFIG Instances” on page
An input port of the ALTGX instance and an output port of the
ALTGX_RECONFIG instance. You must connect the
reconfig_togxb[3:0] input port of every ALTGX instance
controlled by the dynamic reconfiguration controller to the
reconfig_togxb[3:0] output port of the ALTGX_RECONFIG
instance.
The width of this port is always fixed to 3 bits.

ALTGX_RECONFIG Instances” on page
Assert this signal for one reconfig_clk clock cycle to initiate a
write transaction from the ALTGX_RECONFIG instance to the
ALTGX instance.
You can use this signal in two ways for .mif-based modes:
■
■
Connect the reconfig_fromgxb[16:0] of ALTGX Instance 1 to
the reconfig_fromgxb[16:0] of the ALTGX_RECONFIG
instance. Connect the reconfig_fromgxb[] port of the next
ALTGX instance to the next available bits of the
ALTGX_RECONFIG instance, and so on.
Connect the reconfig_fromgxb port of the ALTGX instance,
which has the highest What is the starting channel number?
option, to the MSB of the reconfig_fromgxb port of the
ALTGX_RECONFIG instance.
Continuous write operation—Select the Enable continuous
write of all the words needed for reconfiguration option to
pulse the write_all signal only once for writing a whole .mif.
The What is the read latency of the MIF contents option is
available for selection in this case only. Enter the desired latency
in terms of the reconfig_clk cycles.
Regular write operation—When the Enable continuous write of
all the words needed for reconfiguration option is disabled,
every word of the .mif requires its own write cycle.
