There is a function if you would like to make check and save operation in the extracted view:
dbSetConnCurrent(geGetEditCellView())
Check and save for extracted view

[Cadence Virtuoso] Certain instance of the netlist voltage saving
I have a need in saving all voltages but for certain instance, it can be done with pretty simple approach. You should create .scs file and include it as a model, this file should contain next string:
save * "/path to your instance"
MMSIM 7 doesn’t work in debian/ubuntu
Solution:
Go to /bin, find link @sh and change it from dash to bash.
In usr/lib/ make link @libc.a to /usr/lib/i386-linux-gnu/libc.a
Error libMrm.so.3
As it turned out, in Suse this problem solves pretty simple – just setup openmotif package.
Capacitance measuring with AC analysis
Sometimes I want to calculate capacitance of test device (transistor, varactor, etc). To do it, I create next testbench:
How to connect spectre model in cadence virtuoso
If you have a spectre model which you want to connect to symbol and simulate it all:
1. Create the symbol (pin names should not begin with numbers, although in model text pin names can be numbers).
2. Click Save as and save symbol as spectre view.
3. Go to icfb -> Tools -> CDF -> edit (Base level) add parameter “model” (paramType = string, parse as number = no, parse as CEL = yes) and give it any name.
4. In simulation Information -> spectre set Other parameters in model and in TermOrder put all pins in right order.
That it, we’ve done with symbol. In your testbench just go to properties of our device and give model name for “model” field. Also, you should connect this model in “Model libraries” menu. Now you can simulate your spectre model 🙂
If you want to connect spice model, instead of spectre, then just put next string at the top of model text.
simulator lang=spice
