We have added a frequency Counter IP and connected it to our test signal sources and to Vivado labtiools labtools VIO (Virtual Input Output).

Step xZ:

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.

Two additional clocks generated by the Clock Manager in the Zynq PL are also correctly measured.

But is the clock really 800MHz? Lets try to measure it with some other methods!

Measurement setup 1: OZoM-A is powered from lab supply, power consumption 0.76W, 800MHz clock is connected to signal in the header, Signal hound with air-loop is used to measure the frequency.

Here it is the generated 800MHz signal has been measured to be really 800MHz. Well but maybe this is harmonic and not the signal itself?

Here is more proof that there really was a 800MHz signal that we measured.
