NIOS II time out??

hi,

I have a question about nios2:

Does nios II has a time out, after which the processor is out of service and not responding?

If yes, how long is this time?

thanks for all members

    If you don't have a license, the Nios processor will work as long as the Jtag cable is connected. If it's deconnected, it will last for a certain time, before disabling itself. I think it lasts for one hour.

    You can instantiate an "ocp timout indicator" megafunction, which you can connect to a LED or another I/O, and it will indicate if the Nios processor has been disabled.

    Have a look at application note 320 (http://www.altera.com/literature/an/an320.pdf) for more details.
