Critical Issue
Description
CPRI IP cores that target an Arria II GZ, Stratix IV, or Stratix
V device fail recovery timing. Specifically, the path from the rx_digitalreset_cpri_clk_sync2 global
reset signal to the internal local_reset signal violates
the IP core timing requirements.
Resolution
To work around this issue, in your Quartus II Settings file (.qsf), add the following assignment to demote the global reset signal:
set_instance_assignment -name GLOBAL_SIGNAL OFF -to *rx_digitalreset_cpri_clk_sync2
This issue will be fixed in a future version of the CPRI MegaCore function.
