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.
In reply to dmay:
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!
In reply to J Wilwert:
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
In reply to Quek:
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!
Hi JohnHere are the steps:In the outFile form, please do the following:a. Fill in the name of a new libraryb. Enter a path for the new libaryc. Enter the name of the tech libraryd. For "Assura layer name", enter the name of the layer that appears in the rules filee. For "Layer name", enter the name of the layer that appears in LSWf. Add the layer to the text boxg. Repeat for all other layersPlease see the sample below. : )Best regardsQuek
Thanks - So how do I get to this form? Where can I find it?
Also, I suspoect that this form writes or appends a file somewhere. Maybe, I could just write or append the file.
Hi JohnAt the end of the lvs form, please enable "View Additional Function". Then enable "Create New Database" option and press the button.Best regardsQuek
Thanks - I found the form and followed it through.
I guess I need to back up a little and clearify a point. The net I need to plot may be any net a designer chooses. So it may ot may not have a pin on it. In the past, I've just placed an "X" on the net using the TEXT.drawing layer. It think this slightly changes the code above. Could you help me get this coding correct? Sorry for this oversight.
Hi JohnPlease use this:layerDefs( "df2" myText=text("TEXT") ...)geomConnect( ... label(myText m1) ...)The above would create net labels instead of pin labels.Best regardsQuek
Cool !!!! All is good !!
I've checked the .rsf file and it looks like everything is there that I need to automate this!
Thanks for all your help,
The assura syntax look similar to DIVA syntax..
So, can i use DIVA instead of assura to perform the task mentioned?
BTW, does skill executes "drcExtractRules" ?
or in other word, can i execute DIVA in skill using drcExtractRules ?
I'm currently executes DIVA in skill using ivDRC....
