You EE types seen SignalTap? Looks pretty neat but I missed a couple of things...

1. How much room should you reserve for the instantiation of the SignalTap block?
2. Do you have to use JTAG or can you packetize the data to ship out over an alternate method (ethernet frames maybe?)
3. Assuming you start your design including the SignalTap megafunction, how much re-compilation (if any) is necessary if you change the signals you want to watch?
4. Does the megafunction slow the rest of the 20K device it's in down at all?
5. Does Xilinx have anything like this in the works?
