Hello Brais, The HDL design does have a top block and is composed of usefully divided sub blocks. It is not however designed using the graphical Vivado workflow, but a source based one. Here is the top block: https://github.com/EttusResearch/fpga/blob/maint/usrp3/top/e300/e310.v
Your application however sounds exactly like what the RFNoC architecture was designed for. This architecture, which the E310 implements, allows you to add in a self contained block of functional logic wrapped by an interface supplied by Ettus. I recommend reading this application note and possibly watching this video which introduces the architecture and leads through the creation of a sample RFNoC block. https://kb.ettus.com/Getting_Started_with_RFNoC_Development https://www.youtube.com/watch?v=j-EfyPVpaJ8 If you only want to add a filter or two there is already an FIR block which you could either directly make use of or make hopefully minor modifications to meet your needs. https://github.com/EttusResearch/fpga/blob/6996ed662e5ae170e60ab8cb6de54c362cecf8d2/usrp3/lib/rfnoc/noc_block_fir_filter.v#L141 Regards, Derek On Thu, Sep 21, 2017 at 4:48 PM, Brais Ares via USRP-users < usrp-users@lists.ettus.com> wrote: > Hello, > > We want to add some blocks to HDL design in E310 device.
