ALTGX and ALTGX_RECONFIG Interface Signals
reconfig_fromgxb
Port Name
Output
Input/
Input
An output port in the ALTGX instance and an input port in the
ALTGX_RECONFIG instance. This signal is transceiver-block based.
Therefore, the width of this signal increases in steps of 17 bits per
transceiver block.
In the ALTGX MegaWizard Plug-In Manager, the width of this signal
depends on the following:
■
■
For example, if the channels in the ALTGX instance are regular
transceiver channels and if you select the number of channels as
follows:
1 ≤ Channels ≤ 4, then the output port reconfig_fromgxb =
17 bits
5 ≤ Channels ≤ 8, then the output port reconfig_fromgxb =
34 bits
9 ≤ Channels ≤ 12, then the output port reconfig_fromgxb = 51
bits
However, if the channels in the ALTGX instance are PMA-only
channels and if you select the number of channels as follows:
Number of PMA-only channels = n, then the output port
reconfig_fromgxb = n*17 bits
For example, reconfig_fromgxb = 6 * 17 bits for 6 PMA-only
channels.
In the ALTGX_RECONFIG MegaWizard Plug-In Manager, the width
of this signal depends on the value you select in the What is the
number of channels controlled by the reconfig controller? option
in the Reconfiguration settings screen.
For example, if you select the total number of channels controlled
by ALTGX_RECONFIG instance as follows:
1 ≤ Channels ≤ 4, then the input port reconfig_fromgxb =
17 bits
5 ≤ Channels ≤ 8, then the input port reconfig_fromgxb =
34 bits
9 ≤ Channels ≤ 12, then the input port reconfig_fromgxb = 51
bits
Whether the channels configured in the ALTGX instance are
regular transceiver channels or PMA-only channels.
The number of channels you select in the What is the number of
channels? option in the General screen.
