[Ngspice-users] Parametric simulations

[Aldo R. <ar...@de...>]

Hello everybody,
I'm just new to ngspice, and after reading some documentation I was 
wondering how I may run parametric simulations, sweeping some circuital 
parameters. For example, in the netlist below I may want to sweep 
R_value and run a simulation for each value of the parameter, and 
display all the traces to the same plot.

VIN 1 0  1 AC 1
RL  1 2  R_value
CL  2 3  1u
.AC DEC 10 1 10k


Do you have any hints or suggestions?  Thank you very much!
Aldo
