18 years agoI am not sure what 'compatible' means in this case.
If you have read in the official JTAG 1149 standard that it says TCK should be pulled up and in the schematics you see pull downs, then clearly they are different. I would read several Altera Users Guides and perhaps also look into the pinput report from a design and see if there is any mention on termination in there. I do know that Altera definately tells you to terminate it and it may just be that Altera has decided that terminating it low works best for their designs? The information t hat I have received for Stratix II and Stratix II GX (of which Arria GX is a varient) is as follows; Connect this pin to a 1K Ohm resistor to GND. Glad to help out. How about some Reputation points?? (link on the Blue line above one of posts.) Randalls getting close and Brad & Rysc are pulling away...
