Power extimation?

[Raghavendra]

Hi All,
How to manually estimate dynamic power consumption of the design in the FPGA?
Thanks in advance,
Raghavendra.S

Xilinx has a power estimator utility for their parts. Some other vendors may
have suggestions as well. try contacting their FAE's. By default their are
no "one-size-fits-all" models, only estimations, worse/best case etc.

Hi Raghavendra,

You can access Xilinx's Spreadsheet Power Tools and Web Power Tool (WPT) here :
http://www.xilinx.com/ise/power_tools/. That web-site also provides information
on our desktop power estimation application XPower - which is part of ISE.

Regards,

Brendan

Raghavendra,
When using Altera parts, you have a few options:
1. This web page:
http://www.altera.com/support/devices/dvs-timing_power.html
shows the various online calculators that we have for our devices.
These are spreadsheet-based; you enter information about your usage of
the device, such as fmax, LE count, IO standard used, and so forth. It
reports your power consumption, and also gives some information about
whether the package you have chosen can dissipate the heat that will
be generated.

2. Quartus II software generates a file based on your design which
includes the info needed to populate the spreadsheet. If you have
already compiled your design, you do not need to manually enter the
info, instead you can just take the file from Quartus II. This
procedure is explained in the "Early Power Estimation" chapter of the
Quartus II Handbook:
http://www.altera.com/literature/hb/qts/qts_qii53006.pdf

3. Quartus II software includes a simulation-based power estimation
tool. This takes your simulation vectors into account when estimating
power. This tool is described in the "Simulation-based Power
Estimation" chapter of the Quartus II handbook:
http://www.altera.com/literature/hb/qts/qts_qii53007.pdf

Sincerely,
Greg Steinke
Altera Corporation

Launch XPower from Xlinx project navigator, if you're using Xilinx.
