Arria V Hard IP for PCI Express IP Core Speed Grade Support

Description

By default, the Quartus II software selects an Arria V GX -6 part for the Arria V Hard IP for PCI Express IP Core. However, the Arria V GX device only supports -4 and -5 speed grades.

Arria V GT devices can also support the -6 speed grade if you add a Synopsys Design Constraint (SDC) for the Transceiver Reconfiguration Controller IP Core clock, reconfig_xcvr_clk, to top_hw.sdc.

set_false_path -from [get_ports {reconfig_xcvr_clk}] -to [get_ports {hsma_clk_out_p2}]

Resolution

This issue is fixed in version 14.0 of the Quartus II software.
