IP_Flow 19-627 Port 'o_wb_addr': XPath expression failed: Undefined parameter "AW" used in expression "(AW - 1)".

this happens when trying to use IP wizard, not yet clear what the fix should be for this

this error comes in simulation files, so not relevant for the IP core itself

The error is the result of not defining the address width of the wishbone side of the interface. This is what "AW" is about--address width. You should be able to see that in the definition of o_wb_addr.

<P>To make matters worse, there are some unchecked dependencies between AW, C_AXI_ADDR_WIDTH, and the data width parameters C_AXI_DATA_WIDTH and the wishbone data width DW. Hence, when you set AW, make certain you set DW as well.
