What transceiver slew rate settings are allowed in the Quartus II software for Stratix V GX and Arria V GZ devices? - What transceiver slew rate settings are allowed in the Quartus II software for Stratix V GX and Arria V GZ devices? Description The following transceiver slew rate settings are allowed in the Quartus® II software for Stratix® V GX and Arria® V GZ devices. Protocol/Datarate Allowed Quartus II Setting IBIS-AMI Setting PCI Express Gen3, Gen2, CEI 4 *_30ps PCI Express Gen1, XAUI 3 *_50ps Gigabit Ethernet 1 *_160ps =<1Gbps 1, 2, 3 *_160ps, *_90ps, *_50ps 1Gbps - 3Gbps 2, 3 *_90ps, *_50ps >3Gbps - 6Gbps 3, 4 *_50ps, *_30ps >6Gbps 4, 5 *_30ps, *_15ps Assigning an invalid slew rate will result in an error message similar to the one below. Error (15001): Assignment XCVR_TX_SLEW_RATE_CTRL of value "4" conflicts with the valid values of the parameter "pm_tx_slew_rate_ctrl" Protocol declarations take priority over datarate. For example, XAUI has a per-lane datarate of 3.125 Gbps, but only a setting of "3" is allowed. A setting of "4" is not allowed for XAUI. For protocols not listed in the table, you should use the slew settings associated with your datarate. The IBIS-AMI slew rate figure is defined as the approximate transmitter 20% - 80% rise time. The "ps" figure should not be considered quantitative and is an approximate label only. The IBIS-AMI models will allow you to simulate any slew rate setting for any datarate or protocol.
