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,
Kamesh.

 

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
degree
of accuracy, the power consumption for a particular stream of
data/address/r/w/rthw
combinations. Later you could create fit data(second degree should be
fairly
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
equation
based modeling).
