The following waveforms show the behavior of lpm_counter megafunction for the chosen set of parameters in design count4.v. The design count4.v is a 4 bit up modulus 10 counter. The counter has an asynchronous clear input.
The output port cout will be asserted at the completion of count sequence. The ports cin and cout are used to chain multiple counters together.
The output port cout will be asserted at the completion of count sequence. The counter counts till the modulus value 9.
