The following waveforms show the behavior of altsyncram megafunction for the chosen set of parameters in design cfram.v . For the purpose of this simulation, the contents of the memory at the start of the sample waveforms is assumed to be ( 0, 1, 0, 0, 0, ...). The design cfram.v has two read/write ports. Read/write port A has 2048 words of 8 bits each and Read/write port B has 2048 words of 8 bits each. The ram block type of the design is . The output of the read/write port A is unregistered. The output of the read/write port B is unregistered.
