2013.4 Vivado - critical warnning:[BD 41-237] Bus Interface property MASTER_TYPE does not match when packaged IP includes a BRAM

Description

I have packaged an IP which includes a BRAM, then connected this custom IP to axi_bram_ctrl in IPI.  

The below critical warning is reported when I validate the design.

Critical warning:[BD 41-237] Bus Interface property MASTER_TYPE does not match between /ramtop_0/bram_ctrl(OTHER) and /axi_bram_ctrl_0/BRAM_PORTA(BRAM_CTRL).

MASTER_TYPE in both of the bus properties is gray and cannot be edited.

Solution

You can add a bus parameter named MASTER_TYPE with the value set to BRAM_CTRL when packaging the IP as in the below example:
