I would like to trace a net through the layout heirarachy and then plot the traced net. I have done this with a DIVA script, and would like to rewrite the script using assura. Possible? I need a little help getting started as I am not well versed in using assura. These traced net plots are very useful. Many thanks in advance,
If you are running Cadence 6.1.4 and the nets are not that big (not supply nets), then you can use Connectivity->Nets->Mark Net, and then use Connectivity->Nets->Save All Mark Nets to save the results to a cell. You could then plot the new cell.
I'd really like to say that I'm using Cadence 6.x! Well, that is not exactly true. Do you have any ideas on making this work in Cadence <6.x? (5.1.x) THANKS!
Actually, we are still using 5.1.41.x and don't know when we'll be on 6.1.x. I just happen to know about that particular feature and knew it would be easier than a new ruledeck for Assura. We use a third party verification tool to extract our supply nets for separate viewing/plotting. Unfortunately, I can't help you with Assura.
Hi JohnPerhaps you can code something similar to:drcExtractRules( layerDefs( "df2" m1=layer("Metal1") m1Pins=textToPins("Metal1") ... ) ;layerDefs geomConnect( via( cont m1 poly psub ... ) label( m1Pins m1 ) ) ;geomConnect vddM1=geomGetNet(m1 "VDD") vddM2=geomGetNet(m2 "VDD") ... vddM8=geomGetNet(m8 "VDD")) ;drcExtractRulesNow
open drc and set avParameters ?outputErrorLib to "Output Error Lib". In
"View Additional Functions" secton of the drc form, please select
"Create New Layout Database". In the outFile form, save lvs layer
"vddM1" ... "vddM8" to the actual DFII layers. Now run drc. You will get
a new library with the vdd net.Best regardsQuek
Thanks for jumpimg in on this - I really appreciate the help.
Everything looks good. I am down to the part:
In the outFile form, save lvs layer
"vddM1" ... "vddM8" to the actual DFII layers.
How (and where) do I do this? I am stopped cold on this part. Any thoughts?
Again, THANK YOU!
