Power consumption simulation of a device

Is it possible with Matlab/Simulink to simulate the power consumption
of a system in active mode, sleep mode and hybernate mode, related to
the operating frequency of the system clock?
I have a wireless sensor, built with a microcontroller, some sensors
(temperature, light, and so on), a wireless transceiver.
For every component I would build a block, for simulating the power
consumption in different operating modes (active, idle, sleep,
hybernate).
The current and voltage values are known, by means of tables or
equation.
The simulation timing considers a timing for putting the system in
sleep, wake up the sensors, the microcontroller, the transceiver,
send and receive data, and go back in sleep again. I can parameterize
all the time durations.
In this simulation timing I must see the Power consumption rising in
the active phase and falling in the sleep phase.
Is it possible to do with Simulink a component (black box), in which
I can set the state in a given time(active, sleep, hybernate, ecc.),
the voltage Vdd and the frequency of the clk, Fclk, in order to
simulate the different power consumptions?
