Syntax
set_instance_assignment -name XCVR_A10_TX_SLEW_RATE_CTRL <value>
-to <tx_serial_data pin name>
Note: Currently, the Quartus Prime software doesn't choose the default values for Non-PCIe
mode. You must specify the setting in the .qsf file.
8.7. Transmitter Pre-Emphasis Analog Settings
The programmable pre-emphasis block in the transmit buffer amplifies the high
frequencies in the transmit data to compensate for attenuation in the transmission
media.
Note: Ignore all the pre-emphasis QSF assignments for PCIe Gen1 and Gen2 if your
transceiver link is within the PCI Express spec requirements. Quartus Prime assigns
default values for these parameters.
