Tutorial—Using Power Analysis for Static Leakage Analysis of a PLL Circuit<br />

As shown, the Power Analysis tool has been automatically configured to filter the Name<br />

column with the XPD block as specified in the SPICE netlist (.power_analysis<br />

filter(name)=xpd).<br />

The power consumption of block XPD has decreased from 173μW (see step 6) to<br />

217nW (here) by reducing the slope of the power supply ramp from 1ps to 900ns.<br />

Results<br />

This tutorial showed how to use the Eldo .POWER_ANALYSIS command to visualize the<br />

power consumption of a PLL design for the whole circuit and for the phase detector.<br />
