How can we extract the package (bondwire) model after testing the chip?
If not, how to modify the LNA VCO design for the next tape-out?

I design a LNA. Firstly, I don't added any bondwire effect (1nH in series with 1ohm to pretend a bondwire) on each pad for the simulation. Afterwards, I added the bondwire model at each pad and do the simulation again. I found the NF is 3dB higher compared to the LNA without bondwire (...)

Is there a possibility to simulate the inductivity and other effects of bondwires in ADS Momentum?
The bondwires from my chip down to the microstrip line on the substrate are about 1mm long. But there is only direct current.
thanks in advance,

If i have 1mm of bondwire, its approx 1nH of inductance.
what if i have 2 bondwires right next to each other connected to the same pad, what is the approximate inductance ? (theres going to be some mutual inductance).

You don't need to look this up from a book. The packaging information from you resource should provide you the resistance of a bondwire per unit length. Add that to your bondwire model on series with the inductance. This is simply the metal resistance so will be quite small but would damp out your ringing sufficiently. (...)

Indeed this is a hard thing to do, you only have S11,S21,S21 and S22 measurements although at different freqs, and many parameters to tweak ...
To find approximations for the extrinsic components I would refer to the package parasitics. The length of the bondwire etc depends on the physical structure of the package and can be approximated. That'
