    Yes, I have used Tcl to verified a design that included a virtual JTAG interface that accessed embedded TDRs. To run the actual hardware, I wrote Tcl scripts and used Intellitech's free software tool, NEBULA. It has full Tcl support and even has an integrated Tcl single stepper. You can download it at the Intellitech website. You'll need a Xilinx Platform Cable USB pod too, but you may already have one. If not, they are affordable. Let me know how you make out.

    p.s. Sorry that I can't post links to the free download to this forum yet, but you can search the internet for "free jtag intellitech" and the link should show up.
