<h2><CENTER>Sample behavioral waveforms for design file lpm_counter1.vhd </CENTER></h2>
<P>The following waveforms show the behavior of lpm_counter megafunction for the chosen set of parameters in design lpm_counter1.vhd. The design lpm_counter1.vhd is a 4 bit up modulus 8 counter. </P>
<h2><CENTER>Sample behavioral waveforms for design file "lpm_counter1.tdf" </CENTER></h2>
<P>The following waveforms show the behavior of lpm_counter megafunction for the chosen set of parameters in design "lpm_counter1.tdf". The design "lpm_counter1.tdf" is a 12 bit up counter. </P>

<P><FONT size=3>The counter counts till the modulus value 7. </P>
<P><FONT size=3>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. </P>
