MIG v3.4 Spartan-6 MCB LPDDR - MIG generated ise_flow.bat script file is missing the Bitgen command to create a bitfile

Description

MIG generates an "ise_flow.bat" script file in the output "example_design/par" and "user_design/par" directories. 

When invoked, this script file runs the design through synthesis, implementation, Trace, and BitGen resulting in a bitmap file to download to a board. 

For Spartan-6 FPGA LPDDR in MIG 3.4, the BitGen command is missing in the ise_flow.bat script and should be manually added. 

This only affects Spartan-6 FPGA LPDDR designs generated for the XST flow (Synplicity designs not affected).

Solution

The following command needs to be added to the ise_flow.bat script file to generate the bitmap file.

 

For an example design:

bitgen -intstyle ise -f mem_interface_top.ut example_top.ncd

For a user design:
bitgen -intstyle ise -f mem_interface_top.ut <component_name />.ncd
