Description

My ISE/EDK project contains a MicroBlaze processor submodule. When I run NGDBuild from Project Navigator, the following error occurs: 

"Processing BMM file ... 
ERROR:NgdBuild:927 - Failed to process BMM file edkBmmFile.bmm" 

This issue was not resolved with (Xilinx Answer 21458) and (Xilinx Answer 22205).

Solution

Resolution 1

To resolve this issue, change the XST hierarchy separator from an underscore "_" to a forward slash "/" as follows: 

1. Right-click on the Synthesize - XST process and select Properties. 
2. Select Synthesis Options. 
3. In the lower right corner, set the Property Display Level to Advanced. 
4. Change the Hierarchy Separator from "_" to "/". 

Resolution 2

If the "system.xmp" file is instantiated in a VHDL generate statement, the path in the BMM file will be incorrect. Following is an example of an incorrect BMM path:  

<top_level>/<system_instance_name>/ppc_core/bram1/bram1/ramb16_0 [31:30] ; 

The correct path in the BMM file is as follows: 

<top_level>/<generate_label>.<system_instance_name>/ppc_core/bram1/bram1/ramb16_0 [31:30] ; 

To prevent the ISE tools from over-writing the modifications that you made in the file, mark the file as "read only".
