Scott,

It may be more appropriate to ask these product or vendor-specific questions
directly to our XTK support team (xtk-support@viewlogic.com)...But since its
already out there, I'll respond:

(this == program the programmable pins)

The released implementation requires that you program the pins before
launching the batch run. However, it's possible to create an XTK command
file that changes the parameters between multiple batch runs.

If your desire is to SWEEP through all the programmable models, your best
bet is using a more up front, design-oriented, schematic-based XTK add-on
tool like "Scratchpad" which uses XTK as a back end and can then plot the
sweep results as a solution space (e.g. overshoot/delay/etc. vs
programmable_device vs TLine length) in 3D.

We are bundling the Scratchpad tool "free of charge" with XTK to all
existing XTK customers on maintenance as well as new XTK customers. The
details are still being worked out. Distribution will occur in late August.

Hope this Tool plug hasn't offended anyone since it answered a direct
question.
