Hi,
I am trying to see if there is an electronic analysis software that allows a circuit to be uploaded and I would be able to put in a input at what ever location there is input, then it gives me outputs at various points and I can see what could be wrong.
I found https://www.circuitlab.com/ - but is there something else that could be more tailored to the requirement.
Thanks.
Srinath.

Hi,
TinaTi is a great free circuit Emulator. It is SPICE based
so a circuit described in SPICE terms can be uploaded.
It is not browser based, it is a free standing PC program.

Its a downloadable program, but LTSpice (free from Linear Technology - Home Page) does many of us here very well. TI has something similar too, but I've not tried it.
<edit> I see sreten has already pointed you to TINA.

Hi,
FWIW I've tried both and find TINA easier to use, though I've
never done anything really complex in either. TINA started off
as a teaching tool developed in Eastern Europe academia,
perhaps that is why I find it more accessible than LTSpice.

I've got LTSpice installing in my PC @ this very moment.
I'll post how it goes.
I have not just amps to diagnose, and being my only knowledge of electronics comes from smelling solder fumes in the last couple years and asking you guys, I'll be in trouble no matter what ... But hey what better way to learn.
Cool.

Ok now I have the circuit in .png format.
I need to have it as a schematic file - .asc for LT spice to read it.
How to convert it.
Thanks.

I've never tried to input a ready made schematic into LTSpice myself, rather I draw it using LTSpice.
@sreten - I'm intrigued by how the pedigree of a piece of software may influence its perceived usability. Care to elucidate on the ways TINA suits you better than LTSpice and how those aspects relate to its phylogeny?

by entering the circuit by hand with the LTspice schematic entry tools
no company is really keen on offering interoperablility between their and competitors tools for the same job
I believe you can convert between Eagle schematic files and LTspice with scripts created by the users

Hi,
I'd say just try it yourself. I found TINA easier to work
out how to do things but YMMV if your used to LTSpice.
rgds, sreten.
Just had another look at LTSpice, yuck, compared to Tina-Ti IMO.

LT Spice is very customisable, and may well be a better choice than the free version of TINA, provided that you are an experienced user, and are familiar with the syntax and laborious commands. The free version of TINA is very much easier to use by those who have never used a SPICE program before, but the free version is much more limited than the full (fairly expensive) version. I have the full version at home and use it a lot. I don't have enough hours in the day, or years left in my life, to get to grips with the arcana of LT Spice commands!
Hi,
I agree LTSpice may be more useful to an experienced SPICE user,
but Tina-Ti is so much more friendly regarding a beginner IMO.

OK I guess I'll try to enter it manually.
There is also 1 by digi-key similar to the circuitlab where you enter it manually.
Might go that route.
Cool.

OK I pulled down TinaTI and I managed to get my schematic "pasted into it".
I saved it as a schematic file.
However i cant analyse it, it says its empty ... what should I do to make it see it.
Cool.

It won't work that way, all you did was paste a graphic image into an empty shcematic file. I'm afraid you're going to have to enter the schematic manually.

No electronic simulation or analysis software that I am aware of can use a graphics file with just a picture of a circuit.
But that would be a great programming project for someone who knows image recognition techniques. It would be one way to have a universal schematic-transfer mechanism, since there's nearly always a way to get a graphic image of what's on the screen and save it into a file, even if you have to do a Shift-PrintScreen and then paste it into MS Paint and save it from there.
After the "application-agnostic" schematic-image-recognition portion of the execution was complete, and the circuit's net map and component types and values were stored in the software's native internal format, then one of the add-ons that converted that into some particular application software's circuit-description format could convert it to one of the supported types, such as .asc.
If it was programmed well, it would be as easy as possible for other people to create the software-specific converter add-ons.
