Generating routing statistics

archive

Hi,

I am looking for a way to generate the net lenght for power, clock and signal nets per layer. Does anybody know a way to do that and is there any pre-requisite. I assume that the DEF attribute are all that is needed.

Typically I would like to generate a table with

METn

Thanks for your help,
Eric.

  • 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.
