Default Electronic analysis software

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.

rgds, sreten.

SPICE-Based Analog Simulation Program - TINA-TI - TI Software Folder

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.

rgds, sreten.

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.
Srinath.

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.
Srinath.

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!
