Estimating power consumed by a SRAM for each input vector.

    Dear all,

    I have the layout of the RAM and I will be simulating the circuit by
    passing input vector stream to the RAM. I would like to know how can I
    estimate the power consumed by the RAM for each particular data in that
    vector stream (when I write into the RAM or read from RAM). Based on
    this I need to create a data dependent memory model (as a function of
    the zero/one-ratio of the input data).

    Thanks and Regards,

    Hi Kamesh,

    I do understand your need to create an accurate power library model
    for your
    SRAM. I feel it would be much easier to do it, if you have already
    created a critical
    path model for your SRAM, from which you could easily predict with fair
    of accuracy, the power consumption for a particular stream of
    combinations. Later you could create fit data(second degree should be
    sufficient) with the numbers from the power characterization. After
    that you could
    implement the final model in ALF/OLA(which do have the provision for
    based modeling).
