Preface
Making a frequency counter is nothing fancy? Yes, but how about to create specialized frequency counter hardware with say up to 16 channels with max input clock rate >= 800MHz within 10 minutes? And verify this software defined hardware in the next 20? And implement this on open source software defined hardware platform?
Step 1:
Step X:
We have added a frequency Counter IP and connected it to our test signal sources and to Vivado labtiools VIO (Virtual Input Output).
Step x:
Result: it works from idea to result no trial and error, no just do it, try it out and it just works. This was the very first project on the open source software define hardware OZoM Model-A.
There are 12 frequency measurement channels implemented, connected to ZYNQ Fabric Clock, to both Zynq PS Timer wavegen outputs (no frequency as those timers are not initialized) and to two Clock Manager MMCM that generates two clocks.
