Problem with PowerPlay Power Analyser

Thanks. You are right.

I generated gate level code (.VHO) from VHDL code

using Quartus. Quartus also generated a .do script to compile the code in ModelSim. Then I simulated the gate level code with RTL stimulator in ModelSim and generated VCD file.

The power confidence level was High.

Below are the steps that I used to calculate power, hope it will be useful for beginners.

-----------

DUT = design for which we want to measure power

STM = stimulation vectors

TOP = wrapper for DUT and STM

1. write DUT, STM, TOP. simulate using ModelSim. See wave form to verify

2. In Quartus, Make project with only DUT file, compile

3. In Quartus, Assignment->Settings-> EDA Tool -> Simulation

Tool name: ModelSim Altera

[check] Run gate level --will creat gate level .vho file (we need to make VCD from gate level DUT)

--also will creat a .do file of how to compile it in ModelSim

language: vhdl

[chk] map, [chk] glitch

OK

2. Compile design, Modelsim will open autometically, quit

3. Lunch ModelSim

set directory

File->load--> .do file (to compile .vho file of DUT)

remove "FOR ALL" statements from TOP file

compile stm, top

Simulate->start simulation

select TOP

in VSIM prompt:

vsim> vcd file my_vcd.vcd

vsim> vcd add -r /*

vsim> run 2000ns

vsim> vcd checkpoint

vsim> quit -sim

4. In Quartus --> Assignments-->Settings-->powerplay--> assign VCD file [entity DUT]

[chk] write saf [chk] write block [chk] glitch

5. processign ->start--> powerplay

6. Tools--advisor-->powerplay (for more optimization)
