Hi 

 I am trying to run a project in NiosII Ide tool version 8.0. I am getting the following error.   Using cable "USB - Blaster [USB-0]" ,device 1, instance 0x00 Pausing target processor : not responding. Resetting and trying again : Failed Leaving Target processor paused.   The project i am trying to run includes multiple processors.I am not incurring any problems while downloading the .sof file or compiling the c files.   please help me out   Thanks&Regards   Nksom

Check that the CPU receives a clock, that its reset signal is not active all the time, and that you don't have a custom component that freezes the Avalon bus. You can use signaltap probes to check all that. 

Check also that you have the license for the Nios processor. I had this problem recently: we have a single floating license for the Nios, but we are several working on different projects at the same time. When I compile the design, if the Nios license is already in use during the synthesis phase, Quartus doesn't stop. It just puts a warning saying it couldn't get a license for Nios, and continues compiling everything, with a disabled CPU. It took me a long time to understand what was happening...

It may seem obvious, but often when I get that message, I think it's due to the FPGA not being powered properly, or one of the JTAG lines not making a good connection. I've also had USB Blasters that haven't always worked perfectly, so if you have another one, you could try switching them.
