Dear Mr. Garcia,

 

I am new to Eagle. Currently I am using the 7.7 free version on Mac.

I want to make a schematic and then export its netlist so that I can

use it in MacSpice. However, I can't find a voltage source that can

give me a generated wave function with a desired frequency. May you

help me?

 

Thank you in advance! Ivan Vlaykov

Eagle is primarily a PCB layout tool, not a generic schematic capture

tool for simulation. Since there isn't a physical device like an ideal

voltage source, you won't find one in the libraries.

Of course there's nothing stopping you from creating such a device in

your own library and adding it to a schematic.

This is true but all the big three vendors have well integrated simulation

add-ons I believe and it makes sense to try to integrate simulation as

closely with your actual schematics as possible rather than having to draw

things out several times in different tools. CadSoft sort of integrate with

LTSpice and did a better job with PCBSim (or whatever it was called) but

the latter is windows only and the former doesn't yet have a fully working

export ULP. I think any efforts that bring better integration of EAGLE and

simulation tools (not just spice but other SI tools, thermal analysis, etc)

is very worthwhile as it's one of the current weak points in my opinion.

This is what I would do. I'd create a library especially for simulation and

add all the source and measure parts into there. These can have various

attributes associated with them to pass to the simulation tool. I'd also

add an attribute to any parts in the library that have spice models

available to specify the model and have a folder in the library to contain

the models. Finally I would write ULP to export a netlist and some UI add

in's to interact with MacSpice.

Best Regards,

Rachael

This is what I am trying to do now. LTSpice has a mac version as well, but it is alwful that is why I am trying to work it out on MacSpice.
