Multiple Nios II and Qsys

Hello, Is there anybody that used/have experience with Qsys to fit five Nios II on a Cyclone IV EP4CE22 FPGA? I could only fit one. I need to use SDRAM controller. I'd like to know how many...

Hey,

I did not exactly get the meaning of above explanation.

I have 4 cores, all Nios-e.

One common JTAG port for all 4 cores.

What I am doing till now:

Reset vectors for all 4 cores are set to SDRAM. When I need to run the application dedicated for a particular core, I do right click -> run as-> Nios II Hardware.

This way I have to run all 4 apps individually and therefore they start at different times.

Is their any way to start them all together ???

Also I am not able to run all cores simultaneously. The newest core being programmed freezes the already running core.

Please suggest.
