    HI @yottabyte, I realize (based on the time stamps) that you figured out the answer to your question before you got a response, but do you mind posting your original question and what you found out so any future users with a similar question would be able to see the answer you (and xc6lx45) found out? Thanks, JColvin

    Hi @JColvin, my question was about choosing the correct Zynq in Vivado when creating a new project for the Zybo Z7-20 (see attachment). This exact label with -1, -2 or -3 at the end you can't find anywhere. But all you have to do (and what probably anybody does anyway, besides me) is downloading the Digilents board files here, so the Zybo Z7 shows up in the list of boards. I thought this is not worth a thread. But maybe there will be another user who won't just open up another tutorial that gives the information about the board files, you're right. Thank you @xc6lx45

    Hi @xzsawq21, The add a module function works with the zynq processor as well. What zynq board are you using? Here is another tutorial for using the custom ip core if you would still prefer to use the custom ip core instead of the add a module function. thank you, Jon

    Hi @xzsawq21, Can you be more specific on what your project is trying to accomplish? Are you trying to show hours and minutes on a seven segment display using microblaze and AXI4 IP cores? You might benefit from using the Add A Module function in the Vivado Block design as described in this forum thread. The add a module allows you to use a Verilog module with microblaze and the AXI bus. thank you, Jon

    Hi, most likely it's the slowest speed grade ("C"ommercial). The faster ones are AFAIK only available in "E"xtended (2, 3) or "I"ndustrial (2) temperature range. https://www.xilinx.com/support/documentation/selection-guides/zynq-7000-product-selection-guide.pdf page 5. As a rule of thumb, the price penalty is fairly substantial, the performance difference is not. Higher speed grades tend to be rare in mass market boards. E.g. see page 27 here: https://www.xilinx.com/support/documentation/data_sheets/ds181_Artix_7_Data_Sheet.pdf "Minimum clock period" -1=2.5 ns; -2=2.26 ns, -3=2.1 ns but there is more to the topic than just this one number. Of course, a design that is built for -2 or -3 speedgrade would be unreliable on -1 (if the bitstream is even compatible - but I can't recall ever seeing any efuse etc bits that would prevent it in hardware)

    Hi @Ehud Eliav, In general, I think the JTAG SMT2 will work where as the JTAG-USB does not support Zynq based boards; you can view Zynq support and the native support from Xilinx on our page here, I don't know what chip you are using though. Adept can load bitstreams that have been previously generated, but it only has built-in support for a limited number of boards, mostly Digilent made boards as well as a few other Xilinx chips; if your chip is not recognized by Adept you would need to do some customization with Adept through Adept SDK which is available on the right hand side of the Adept Resource Center.
