Missing net and Cell Names-exporting gds2 from encounter , importing it in Caliber

 I'm not familiar with this way of running Calibre, but when you say "library file", do you mean the spice subckt files? Make sure the spice of your std cells is included.

 For LVS, you need to use a physical verilog. In Encounter:

 saveNetlist -phys myDesign.v

See if that gets you past this issue.

Hi, 

Unfortunately its not. working. Pls find enclosed the encounter config, encounter scripts. I am using  encounter first time, since I am in student my setup is very basic for academic research purpose (goal was to extract RC+Coup)  in dspf

thanks

Encounter Script

------------------------------------------------------------------------------------------------------------------------------

 First of all, if this is a direct cut-n-paste of your script, you have the -phys parameter of saveNetlist spelled wrong.

But, if all you want is RCs, You can get those right from Encounter.

setExtractRCMode -coupled true
extractRC
rcOut -spf myDesign.spf

The only part I'm not sure about is the last one - I don't know if that will give you dspf or not. (Most people use SPEF these days.)

If you want sign-off quality extraction, you should run QRC, but that may require a bit more setup.

Thans for your reply. Actually, I am getting spf from encounter. But the spef I am getting has all coupling capicatnes included, but spf do not have coupling capicatines. 

I tried detailed mode , with coupling capicitances on option 

We have to feed this to  our code --that does processing, unfortnately it reads only spf/dspf only not spef

thanks
