  • C++ Verification Testbench Best-Practice Resources?
    7 projects | /r/FPGA | 11 Jun 2023
    I have built a lot of open-source C++ tooling for design verification. You can find a lot of my C++ models posted on my Github. Example C++ models include: UART, SPI/DSPI/QSPI Flash, SD-Card (SPI-based interface), VGA Video, Ethernet MDIO, PS/2 mouse, OLED display, SDRAM and more. (I've even simulated PLLs using C++ models ...) I have also written extensively about doing so at ZipCPU.com.
  • Sobel algorithm in VHDL help
    2 projects | /r/FPGA | 17 May 2022
    Most of the graphical images I've seen won't fit in block RAM on on an FPGA. (Think of an 800x600 pixel image, with 8bits per pixel, and it only gets worse from there.) The image needs to be stored elsewhere. That means, you need ports associated with feeding your image to your Sobel processor. This can happen one of two ways. You can either use a external Video frame buffer reader, or you can drive the memory bus yourself. You haven't said what type of memory bus your system has, so let me instead assume the external reader.
  • Any good tips for writing IP that inputs/outputs AXI stream?

    Definitely. To see how this might build up, consider this video sprite module. At each stage, counting from the end, the READY backs up.
  • Simulate FPGA with other ICs
    2 projects | /r/FPGA | 29 Nov 2021
    Ahm ... I've certainly added C components to my test bench to create and simulate graphical interfaces. Here's one for VGA, and another for HDMI. This isn't really a "nobody does this" task. It's much easier to debug a graphical component graphically than it is to debug it with a wave file. Indeed, I owe my success in one particular video decompression example to being able to stop the simulation in real time in order to find and trace a bug.
  • Getting DDR3 working on Arty-Z10

    Pixel packing is an issue. Here's a routine to pack pixels back into words for memory writing.

    This demo shows how the AXI stream framed data can be turned to pixels and sent to a screen--should that be your wish.
