dynamic power

Have a look at the following for Cyclone II devices: powerplay early power estimator user guide for cyclone ii fpgas (http://www.altera.com/literature/ug/ug_cyc2epe.pdf)

Download the appropriate spreadsheet from here: powerplay early power estimators (http://www.altera.com/support/devices/estimator/pow-powerplay.jsp)

Hai Alex,

i tried with power play estimiators but iam getting only thermal power.i need to calculate dynamic power.

already i tried with cyclone II userguide.it is asking to generate vcd file.generated vcd file also.

next step asking to generate sdf file.how to proceed dont know..

Step 1) run a modelsim gate level simulation and set it to generate the .vcd file. The simulation must be long enough and with enaugh variations on the inputs to be representative of the actual working conditions of your circuit.

step 2) change the power analyzer settings abd tell it to use the generated .vdc file

step 3) run the power analyzer. Read the data, Verify the confidence metrics to see if there are signals that are not properly stimulated by your simulation.
