Difficulty using clocks on F-Series Development Kit

I am having a difficult time understanding how to use the clock on the Intel Agilex 7 FPGA F-Series Development Kit (P-Tile and E-Tile) DK-DEV-AGF014EA. I tried creating a simple design to toggle the on-board LED by directly connecting the pins for the 100MHz and 50 MHz clocks to my design. This did not work, but I was able to get the Nios® V Processor PIO LED Toggle Design Example working. I noticed that in this design the s10_configuation_clock ip was used rather than directly connecting to a pin. This worked when I tried it for my own design, but am I going to have to use this IP for all my designs or is there a way to setup the 100MHz and 50 MHz design? I also noticed that the output of the s10_configuration_clock was connected to GLOBAL primitive and was wondering what the purpose of this is.

  • Hi @JackLusenhop ,

    Not sure what aspect specifically is giving you trouble, but here's a simple example design that toggles an LED using the 100 MHz clock on the DK-DEV-AGF014EA board. See attached.

      Hi @sstrell,

      Thanks for the link, I was able to use the IOPLL IP in the guide as a fix to the issue as well. I wonder why instantiating the IOPLL IP had the same affect for me as setting the IO Standard. I will have to look more into it. Anyway, thanks for the help!

    Hi @roeekalinsky,

    Thank you so much, the example design worked. I think the issue was that I did not set the I/O Standard to "True Differential Signaling" for the clock in my design. Have a good one!
