Hi @engineeringNCMXB,

I hope you're doing well. That is correct sir, the webinar is today September 27th at 5PM EDT.

Please let me know if there's anything else I can do for you.

Best Regards,

Hi @crrrack,

That's what I said... just kidding I edited my post to reflect the correct day. The picture has the date wrong, but the text has it right. The webinar is today.

Sorry about the confusion.

Best Regards,

Hi @rg.jones,

I hope you're doing well. It was recorded and should be posted shortly.

Let me know if there's anything else I can do for you.

@edwin.robledo Was this recorded? If it was, is it still available?

Hi @banksysan

there is a recording on our youtube EAGLE channel: https://youtu.be/BCpYbKRfPa4

I hope this helps.

Ah. My Googling found that one. I've followed it along but it skips past the first step, how to create a new digital/analogue circuit in the first place.

In my schema, as soon as I put a digital component and a convertor the simulation never finishes. Could you do a video on just creating a functioning digital/analogue circuit from a new, blank schema?

Hi @banksysan ,

Do you have a schematic you could share of what you are trying to do? It's possible you did everything correctly but if the simulation isn't setup just so you might not get it to converge. In this respect our current implementation is temperamental.

Let me know if there's anything else I can do for you.

Best Regards,

There is a bug in your circuit.

out from X2 is digital.

You then select the A->D converter. It has to be a D->A converter.

You're correct. Sorry, typo from looking at this for too long.

I've corrected that and get the same problem,.

Where would I find that? I only have two files, the .sch and .sch.net.

Re: Simulation in EAGLE is going Digital!

jorge_garcia — Wed, 22 Sep 2021 20:58:29 GMT

Hi @banksysan,

You can find the models for the built in parts in the EAGLE installation directory, inside of examples > spice > examples.

Let me know if there's anything else I can do for you.

Best Regards,

Thanks @jorge_garcia, I'm using the ng-spice libraries and have have the models assigned (I'd get an error if I tried to simulate without those).
