Digital Circuit Simulator

[bearded_badger]

Hi forum, I was wondering what a currently developed digital circuit simulator software for Windows (for a beginner) would be? I started using CEDAR but it crashes with a simple circuit.

The FPGA guys offer low end versions of Modelsim in their basic tools, like Altera, Xilinx.

But learning curve not simple to get setup and running for first time user.

Have a look at Logisim. To quote the web page, "Logisim is an educational tool for designing and simulating digital logic circuits."

It' free and available at http://www.cburch.com/logisim/

You can download a Beginners tutorial and the documentation to see if it's what your after.

Thanks I'll look into both.

Yes, Logism is the nicest free logic simulator I have used.

If you're looking for a simple non-free program, I like using Circuit Wizard for simulating circuits with logic chips (7400 and 4000 series stuff).

Hello,
We've been developing an improved version of Logisim (since the original version is not developed anymore), check it out here: https://github.com/reds-heig/logisim-evolution
Cheers,

You might want to try LogicCircuit. It's free and looks easy to use and pretty comprehensive (check out the sample circuit for the calculator):

EDIT: If you check this post on their forum, someone has written a complete 74xx parts library for it: http://www.logiccircuit.org/forum/viewtopic.php?f=3&t=9628
