Hello,

 

I want to use more then one JTAG to Avalon Masters in my QSYS system.

I want one JTAG to Avalon Master to communicate with DDR3 and the other with a different system component.

 

Is this possible?

Of course. Just connect the master interface of the J2A Master to the slave interface(s) you want. If you're using System Console to access the slaves, you'll need to select the correct J2A master.

 

You could also connect both slaves to a single J2A Master component and set up the address space for that single master appropriately. That would make it easier to access both components simultaneously.
