I had a design that I was running on an FPGA (Cyclone V), which included a PLL and several FIFOs.
I am trying to move the design to Arria 10 PAC. However, I don't know how to instantiate PLLs and FIFOs for use with the Accelerator Functional Unit.
I need the PLL to generate a phase-shifted clock and the FIFOs to store some data for processing.
My questions are:
1) The only thing I found for the setting the clocks of the AFU were the key:value pairs "clock-frequency-high" and "clock-frequency-low", which only set the frequency. How can I generate a clock with a specific frequency and phase shift to use with the AFU? This is particularly confusing since PLLs cannot be instantiated in the PR region where the AFU is.
2) As for the FIFOs, would the correct procedure to follow be to create the IP in a regular Quartus project, and then to include it in the files to be used with the afu_synth_setup?
