<h2><CENTER>Sample behavioral waveforms for design file ROM_99.vhd </CENTER></h2>
<P>The following waveforms show the behavior of altsyncram megafunction for the chosen set of parameters in design ROM_99.vhd. For the purpose of this simulation, the contents of the memory at the start of the sample waveforms is assumed to be ( 3F0, 3F1, 3F2, 3F3, ...). The design ROM_99.vhd has one read port. The read port has 99 words of 10 bits each. The ram block type of the design is M4K. The core uses a different clock enable than the input registers. The output of the read port is unregistered. </P>

<P><FONT size=3>The above waveform shows the behavior of the design under normal read conditions. The read happens at the rising edge of the enabled clock cycle. The output from the RAM is undefined until after the first rising edge of the read clock. </P>
