Question about ngspice

Hi guys! I followed the youtube tutorial on ngspice from:

but I can’t get my KiCad simulator to work. I get “Error: vector time not found!”. I am sorry if the question is already answered, I did not see it anywhere. I think the answer lies in the comments for setting the time. I am using the transient analysis option.

OS: Windows 7 Pro, VMware, Windows 7 Pro host.
Leads to:
which suggests a typo in the “time” net as a hint to look further into.
I needed about 2 minutes to do that, did not read the whole KiCad post.

Unfortunately that does not applies for me. Since I am new to the simulator, I think I am missing some of the steps.

Here is my netlist

This line is not ngspice compliant.

Looking at the netlist, there seem to be more incorrect settings. The first letter in an instance line determines the device that ngspice is going to simulate (see table 2.1 on page 46 of the ngspice manual).

You have
U: Uniformly distributed RC line
T: Lossless transmission line
K: Coupled (Mutual) Inductors

I guess that’s not what you intended.

You have to prepare your circuit with ngspice compliant naming conventions for the devices.

Why not start with the circuit you have shown on the title window of the video? You may find it in KiCad/share/kicad/demos/simulation/laser_driver, ready to be loaded into eeschema and ready for simulation. You may play around with its devices, libs and parameters.

You might also have a look at the step by step approach described in .

Thanks! I will try. I am normally an “OrCad” user and trying to pass to a new simulator.

FYI, if you’re accustomed to PSpice you’ll be sorely disappointed if you use even a little bit of its features. PSpice is a far more mature circuit simulation tool than KiCad and complex circuits and advanced simulation types won’t work at all or will leave you disappointed in KiCad. I’m sure KiCad will close the gap as time goes on but right now it’s a chasm.
