    Subject: [oc] single_port: replace rnw input by nce, noe and nwe inputs
    Top
    Hi Robert (or other users interrested to the single_port model),

    the single_port core presently only has a rnw input signal. That's
    different to real asynchronous RAMs as you can buy them. They
    usually have the following signals.

    nce (not chip enable)
    noe (not output enable)
    nwe (not write enable)

    I think it would be useful to change the interface in this way.
    The model would then also contain tristate drivers as real RAMs
    have. In my present design I had to implement these tristate
    drivers externally. So I could simplify my design by adding the
    above interface. I think this would also be the case for most
    other people who want to simulate an external asynchronous RAM.

    How do you think about it?

    Michael
