JESD204B IP Core ed_synth Timing Failure (Arria V)

Description

The JESD204B IP core design example has a hold time violation to the transceiver.

This issue affects all versions that support the JESD204B IP core.

Resolution

You can use the set_min_delay command to change the absolute minimum delay for the path. The value to apply depends on the negative slack that you see.

For example, in a case where the negative slack = –0.04, apply a value of 0.1 ns (with around 0.06 ns as the guardband).

if {$::quartus(nameofexecutable) == "quartus_fit"} {

set_min_delay -to [get_keepers

{*inst_av_hssi_8g_tx_pcs|wys~BURIED_SYNC_DATA*}] 0.100ns

}
