Re: [USRP-users] how to write test for block with two output ports

Hi ishai, Although a block with different number of inputs and outputs is feasible in rfnoc, uhd won't work well with it so I would suggest you define it with the same number of inputs and outputs and then just connect the unused into to a null source/sink For a complete example on how to

Hi Brian, I think I understand where you're going but I still think you may have more trouble than solutions. One for all is bandwidth. 10g Ethernet is just able to support one channel at 200 msps. Unless you're downsampling somewhere you won't be able to pass all that bandwidth across the

Hi Brian, It really depends on what you want to achieve. If you just want to perform validation then you can use simulation which is already set up and straightforward if you follow the examples. Also it would allow you to verify even hls code and make sure it does what you expect in a cycle

Hi, list, I want the usrp e310 run only one tx path and one rx path (to save some fpag resource) how can I modify the host code and fpga code ? I use the uhd version: ca09fd2bea0128c18eac4b0ff8a9b30fccdf7698 fpga version: 63e630a13fde1735b98eab1f401f60f0b354cafb Thanks.

Hi Brian, Don't think what you want to do is feasible. While the streaming data part is easy as it's basically just an oot block, emulating register writes is not possible because they go through APIs that send commands over the network. The only reasonable option I see to do what you want is
