Pin or signal naming promotion from PCELL connectivity information

sanramz said:

I have generated layout using Virtuoso XL and SDL.

What is SDL?

Is there any way to promote the net/pin names of those PCELLS from the connectivity information it associates??

What do you mean by "promote"?

I didn't understand the question either. SDL probably means Schematic Driven Layout. There is the Connectivity->Nets->Propagate, but if using VLS XL this shouldn't be necessary because the connectivity would come from the connectivity source (the schematic).

So I don't really understand what is being asked (which is why I didn't answer it earlier).

Hi Andrew,

 When I generate the Layout from schematic, all the devices/pcells have the connectivity information associated with it. This connectivity can be seen by NAVIGATOR or ANNATOTION BROWSER.

When I check any one PCELL properties (using css()~>?? ) associated with it, the properties of that PCELL are as mentioned below. 

css()~>??

But here it is not indicating any Source/Gate/Drain connection information. How can I get that info??

 The information is there, you just need to go deeper. Notice that there are three "instTerms":

 instTerms     (db:0x169e6e94 db:0x169e6e93 db:0x169e6e92)

Try:

css()~>instTerms~>??

foreach(it css()~>instTerms printf("inst name: %s   term name: %s  net name: %s\n" it~>inst~>name it~>term~>name it~>net~>name))

Thanks alot Derek!!

 It helped me.
