<h2><CENTER>Sample behavioral waveforms for design file altdpram0.vhd </CENTER></h2>
<P>The following waveforms show the behavior of altsyncram megafunction for the chosen set of parameters in design altdpram0.vhd. For the purpose of this simulation, the contents of the memory at the start of the sample waveforms is assumed to be ( 7, 6, 5, 4, ...). The design altdpram0.vhd has two read/write ports. Read/write port A has 16 words of 3 bits each and Read/write port B has 16 words of 3 bits each. The output of the read/write port A is registered by clock_a. The output of the read/write port B is registered by clock_b. </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 write cycle is assumed to be from the rising edge of the enabled clock in which wren is high till the rising edge of the next clock cycle. In BIDIR_DUAL_PORT mode, when the write happens at the same address as the one being read in the other port, the read output is unknown. Actual write into the RAM happens at the rising edge of the write clock. The clock enable on the write side input registers are disabled. The clock enable on the output registers are disabled. For the A port, When a write happens, the output of the port is the old data at the address. For the B port, When a write happens, the output of the port is the old data at the address. </P>
