Block Description
Editing the ALTGX Wrapper File
If you want to change the settings of the parameters, edit the legal ranges in the
ALTGX wrapper file.
For example, if you want to change the voltage output differential control setting from
4 to 7, change the following line in the wrapper file:
alt4gxb_component.vod_ctrl_setting = 4
to this line:
alt4gxb_component.vod_ctrl_setting = 7
f To know the exact legal ranges for a specific Altera device, refer to the respective
device handbooks.
Using Analog Control
If you want the flexibility to access and control the ALTGX settings, use the
ALTGX_RECONFIG megafunction to enable analog reconfiguration. You can use the
analog control to edit the default settings of the following transceiver parameters:
Voltage output differential
Pre-emphasis control pre-tap
Pre-emphasis control 1st post-tap
Pre-emphasis control 2nd post-tap
Equalizer DC gain
Equalized DC control
The ALTGX_RECONFIG megafunction interfaces with the ALTGX using
reconfig_togxb[3:0] and reconfig_fromgxb[16:0] ports for a single channel.
To enable the analog control and channel reconfiguration during run time, use the
reconfig_mode_sel signal.
f For more information about how to use the analog control with the
ALTGX_RECONFIG megafunction, refer to the ALTGX_RECONFIG Megafunction
User Guide in the respective device handbooks.
