Re: [Ngspice-users] Parametric simulations

[Holger V. <hol...@un...>]

Aldo,

you may do this simulation with the ngspice internal scripting language 
( see the attached file). One still has to figure out while R1 works, RL 
does not, and so on.... All tested on the Windows port of ngspice. In 
fact this capability of Spice is not documented very well. It may be 
o.k. firstly just to present more examples, only then one can create a 
HOW-TO.

Regards

Holger
