Xilinx Xpower Issues - Help from xilinx team please

Hi,

I am facing following issues when using Xpower to calculate the
dynamic power for my design:

Tools being used:
Xilinx ISE 6.2, Xpower 6.2.03i
ModelSim XE II/ Starter 5.7g

I am generating the .vcd file during post PAR simulation and then
using this file for xpower along with .ncd and .pcf files. I get a lot
of warnings like:

WARNING:power:763 - Only 41% of the design signals toggle.

WARNING:power:216 - VCDFile(564214): $dumpoff command encountered, all
simulation data after this will be ignored.

My Questions:
- How come I get clock power zero? In another smaller testdesign of
counters, I do get some power although logic power in that case is
very less.
- The activity rate for clock nets is zero. How?
- I get the correct simulation but the power results seem incorrect.
- Whats the meaningof such warnings?

Mukesh,

Try running 'clean up project files' from ISE then delete any .XML
files that may be remaining in that project directory. The .XML file
contains toggle and frequency data and can conflict with the VCD
simulation file if they don't happen to target the same device. (For
example, you target a Spartan-IIe then save the settings file and then
retarget to Virtex-II and accidentally load the .XML file for the
Spartan-IIe design)

If that doesn't help, send the design into Xilinx for analysis. They
can take a look at it and let you know what the problem is.
Regards,
Arthur

This too looks similar to the other problem which we've been working on.
You could you to zip up the NCD, VCD & PCF files and send them to me. (Or
again wait on the service pack next week.) It would also be helpful to
know if the messages you've provided occured in the sequence indicated
above.

Hi Arthur,

Thanks for the response,
I tried cleaning up as per your suggestion but that didnt help.

Are you really using software that OLD? I tend to use older software,
but recently moved up to version 14. I'm surprised that software even
supports Spartan 3E.

No, roopa is using ISE14. The post he's replying to, however, is 10 years
old...

I've noticed a sudden uptick in these kinds of posts lately - i.e. replying to
5, 10 year old posts. Caught myself answering one on the Xilinx forums before
I noticed how old the thread was...

Think I even saw a 17 year old usenet thread replied to as well.

Must be senior project time, one wonders?

Just kinds of funny to see.

I was going to write something nasty about Google. But I erased it.
