Vivado Labtools do not have Frequency meter.
Who said that? They do now!
Here, TE0710 Art ix module as hardware test bench. Frequency Counter IP Core configured for 4 channels. Reference clock is from 100 MHz oscillator. Just for testing 33.3333 MHz and 800MHz signals from FPGA Clock PLL are connected to channels 0 and 1. Channels 2 and 3 are connected to I/O Oscillator IP Core. Channel 2 I/O pin is "empty" FPGA ball from DDR3 bank with 1.5V I/O Voltage. Channel 3 I/O pin is in 1.8V bank and is connected to on-board Ufl coaxial connector with PCB trace of about 12 mm length.
