Serial RapidIO v5.4 - Example design "implement.bat" file has error

Description

The "implement.bat" file generated for the Example Design with the Serial RapidIO v5.4 core contains a syntax error which cause NGDBuild to fail with the following error: 

"ERROR:Portability:90 - Command line error: Argument "srio_v5_4_x1_vhdl_top.ucf" has an invalid extension. The valid extension is ".ngd". If your file name has more than one "." in it you must explicitly enter the full file name with its extension."

Solution

To fix this issue, this line: 
ngdbuild -sd ..\..\ -sd ..\..\netlists\ -sd ../../example_design/chipscope/ :> -uc srio_v5_4_top.ucf srio_v5_4_top 

Needs to be changed to the following:
ngdbuild -sd ..\..\ -sd ..\..\netlists\ -sd ..\..\example_design\chipscope\ -uc srio_v5_4_top.ucf srio_v5_4_top 

This issue is resolved in v5.5 of the core, released in ISE software 12.1.
