Honored ContributorImplementing an asynchronous counter in a FPGA
I need to implement a 32-bit counter that counts random impulsions in a FPGA. The counter has to be asynchronous (or not?) for the following reasons: - low consumption - to latch the impuls...

Honored Contributorsearch for n-bit counter verilog (or VHDL), lots of examples will flood to your search results.
It does not need to be a gray counter. It makes no difference for you. Any type of counter suffices your need. If your incoming pulses are 10-20 ns, you could certainly use a synchronous counter, clocked by the system clock @ 100 MHz for example (125 MHz for better results). You should be able to pass EMC issues, since this is a typical frequency many EMC-compliant devices are working with.
