What is currently the best A/D simulation software?

Thanks in advance for any info.

LTSPice from Linear is free and well thought of around the newsgroup.

In the low price range, I've been using BeigeBag for years (since they were selling it on 3.5" floppies in real brown paper bags). They've recently done a re-write to the codebase for their V5 release and, while there still are a few rough edges left from the move, it's a good product. Interoperates with Eagle CAD.

Can't help you on the very high end stuff, tho.

"Best" never exists. What are you trying to do?

SuperSpice, a very affordable Mixed-Mode Windows Simulator with Schematic Capture, Waveform Display, FFT's and Filter Design.

Let's make two distinctions:

a. Best for hobby use at a reasonable price, say US $ 300. b. Best for professional use (without taking price in account).

SIMetrix SPICE has a good reputation. It's included with the Pulsonix ECAD software I use.

Here's one for RF & Microwave , AppCAD Version 3.0.2

gerbtool.exe ,

linesim.exe ,

camcad.zip ,

Impedance calculator / PCB stackup SB8000 combined package for multi-layer boards ,

What exactly do you mean by A/D?

OK, and do you intend to simulate A to D converters or are you looking for general purpose simulation software? The best deal out there for general purpose software is LT Spice (aka SwitcherCad) as it is free and works well. You can't go wrong trying it.

If you are willing to purchase a high-end tool for IC design, I would suggest Ansoft Nexxim. Its new algorithms are about 5 times faster than current tools on the market. For example, if you are simulating a PLL netlist for 4 days, you can get the same transistor-level accurate results in less than a day. The same holds for difficult simulations that include post-layout parasitics.
