Hi Mark, Yes, multiple distinct instances of an rfnoc block can be supported.
In the flowgraph, you need to place a component representing each RFNoC block you want to attach to-- then set the "block select" parameter to unique indices. For example, to use two FIFOs, set up with "RFNoC Config" -> "FIFO Select" to be 0 and 1 for your two instances respectively. Flowgraph might look something like this: [image: Inline image 1] Hope this helps EJ On Dec 8, 2017 7:49 AM, "Mark Luscombe via USRP-users" < usrp-users@lists.ettus.com> wrote: P.S. Obviously i have compiled 2 instances of the block into the FPGA image, maybe i need to add some unique identification at this point?
