How to use the Tcl transcripts generated along with the DDR memory controller IP

Hi guys,

I notice there're seven Tcl transcripts generated automatically when a DDR memory controller IP is generated, it seems these transcripts are used to configure the timing and pin assignment for the controller. I'm new to the external memory interface, I wonder if running all/part of these Tcl transcripts is part of the procedure for setting up the external memory controller before full compilation? Is there a convenient way to run multiple transcripts at a time? Also which document should I read to learn how to use these Tcl transcripts?

Thanks
