Critical Issue
In the initial version of the RapidIO II IP core, the rx_cal_busy and tx_cal_busy signals
are erroneously declared as input signals. These signals should
be output signals of the IP core.
To fix this issue in your RapidIO II IP core variation, edit the top-level file <variation>.v and the top-level simulation file <variation>_sim/<variation>.v, or in the corresponding .vhd files, to declare these signals as output signals. The declarations are correct in the RapidIO II IP core internal modules.
This issue is fixed in version 12.1 SP1 of the RapidIO II MegaCore function.
