I haven't used it myself but following are the instructions. Give it a try.. EMU can now be used to measure VDD supply current as the circuit is simulated. Simply ask to plot the node "vdd". Plot can be set up using the command I imax iperiod imax is the full-scale plot current (in mA) iperiod is the period (ticks) over which the current is integrated. Both imax and iperiod default to 1 Note that the instantaneous value of supply current (on a per tick basis) is not meaningful - the exact details of such a waveform depends on the exact distribution of parasitics within the substrate. When averaged over a few switching events, however, it does provide a fairly accurate measure of power dissipation. Mehdi
