Thank you for your reply.
I have been trying to log data with using in system source and probe, and signal tap II tools. The sample period of my control system is 1ms and the major problem is that i couldn't log data at each period. For example I wrote a tcl code for in system source and probe, which reads continuously probes, but it can read data in period of approximately 5ms. In this case some data are lost.
I have been trying to find the information about limitation on speed of jtag.
Now do you have any advice?
Regards
Bedri
