Simulation with EAGLE

[HarrySatt]

Hi

I am new to simulation with SPICE coming with EAGLE. What I would need is a way to simulate with an arbitrary signal (CSV format) just like I can do in PCBsim from FELICITAS. (contacting FELICITAS is not easy at the moment)

In SPICE this is done with a PWL source

V1 PlusInt Minus DC 0 PWL ( 0, -0.00239607 , ......

How to accomplish this with EAGLE SPICE (ngspice)

Thanx for help, harald.

Yes you can .. although the user interface does not have any special input for it, PWL is a perfectly valid source value .. just right click on your source part, and select VALUE, and set the value to 

DC <dc value> AC <ac value> PWL(<your pwl values>)

Example: 

I will make a note to add PWL to the SourceSetup command interface, but for now you just need to use the VALUE command.

Hi

Maybe you also have a solution for the problem of very long timer range of the PWL values. Meaning thousands. I would like to get rid of the value string in my circuit drawing. See below. It is only part of my PWL.

Hi

Sorry. Found the solution myself. I have to smash the device and set the visibility of the VALUE part of the device. All can be done in INFO.

thanx for help

ahh i see you found this out already 🙂 

Yes you can smash the part then set the Display property of the value so it is not visible. 

In fact we already have this planned for a upcoming release so stay tuned.
