Generating routing statistics

Hello Eric,

You can get this summary from the encounter GUI:

Design -> Report -> Summary

You can generate a Text or HTML report.      The following information in the text output is at the bottom of the report.   This is not broken out exactly the way you are looking for though (clk net, special net, signal net)

Regards,

Elvis

Hello Elvis,

I have been digging into this and in fact to do what I want I need a few reports.

The one you mention give me global usage per layer but not a breack down by category.

The trick without advance scripting is that there is no report per category or net giving both special and regular nets so I use the following reports

For power nets
reportPowerStat -detailed -wireonly

For non power nets
reportWire -detail 0

The first report is not very comprehensive as it uses layer number instead of layer name but it is not too difficult to handle.

The second report will have all your routed (included power for tie high/low) and is very usefull if you have some kind of naming convention or generate an associate report (through scripts) classifying the nets per category.

And then finally I use a perl script to process all that.

If anybody has a better solution let me know.

Thanks,
Eric.
