Hey, I have a very novice question and really just need a high level answer, but I'll get straight to the point! I'm using the Zybo z7-10 with Vivado and Vitis 2019.2. This is what I would like to do, and I'm trying to do it in VHDL: Write some data from software to control registers that I define Perform some processing on this data Use DMA to write some results to DDR I would like the firmware piece that does the processing to be a block in the BD. I've gone through many forums, and it seems at one time the preferred way was to package an IP. I found out about adding an RTL module, which seemed more appropriate because I want to be able to modify quickly as I go, and in the same project. Based on what I've read, I was thinking to make an RTL module with a Slave AXI-lite interface (not sure how to do the registers though?), then use a master AXI-stream to pump the results to a Xilinx DMA IP block. I've been passing Synthesis but getting different Implementation errors ("failed to stitch checkpoint", "*.vhd is a black box") doing trial and error with this. All I've done in terms of the code is try to define the entity port to have those two interfaces, either copying from other IPs or using the Language Template (for AXI stream). Is there a good example in VHDL of a barebones AXI peripheral like this, that will pass Implementation? Once that works, I can get into adding those registers and the processing logic. Thank you!
Hello, I've been working on a project that I need to use the ip integrator and add an RTL block that I made. I'm using a Basys 3 board, Vivado 2018.3 and MicroBlaze ip. I was trying to add the RTL to the source and to the diagram and I used the getting started with ip integrator tutorial. The tutorial itself worked fine and when I added the RTL It passed the validation, synthesis, implementation and even generating the bitstream but then I couldn't export hardware for programing the MicroBlaze and it gave an error saying "Cannot write hardware definition file as there are no generated IPI blocks". Correct me if I'm wrong, but I understood that I need to create an ip that contains my RTL project and only then I can add it to the diagram. If so, does anybody have a tutorial of how to make a new ip? and if that is not the case, what do you think is the problem? thank you, Netanel.
