Hi Shoor,
instead of doing the build with our Makefile system, you can[1] also
generate a ISE project (.xise) that you can load in ISE, and build using
ISE:
make PROJECT_ONLY=1 {yourtarget}
In my experience, if anything, this doesn't change the build times
drastically, even for minor modifications to single modules.
Best regards,
Marcus
