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

Prerequisites<br />

• Copy the power_analysis example directory into your working directory by entering the<br />

following UNIX shell command:<br />

cp -r $MGC_AMS_HOME/examples/power_analysis .<br />

Procedure<br />

1. The Power_Analysis_PLL.cir main netlist file is delivered with the .power_analysis<br />

command already specified. Run Eldo on the netlist:<br />

<strong>eldo</strong> Power_Analysis_PLL.cir<br />

2. After the simulation is complete, launch EZwave and open the generated output file<br />

Power_Analysis_PLL.wdb:<br />

ezwave Power_Analysis_PLL.wdb<br />

In the Waveform List panel, expand the Power_Analysis_PLL root folder and you will<br />

see two folders called POWER_TRAN and TRAN.<br />

The POWER_TRAN folder contains all the necessary waveforms used by the Power<br />

Analysis tool. The TRAN folder contains all the usual waveforms related to voltages/<br />

currents.<br />

3. Start the Power Analysis to identify which PLL components consume power. Expand<br />

the POWER_TRAN/Power_Analysis_PLL folder, right-click the XPLL subfolder and<br />

choose Power Analysis from the popup menu:<br />

This opens the Power Analysis dialog box:<br />
