use matlab maybe the best
here a matlab program to calcute the opamp transfer function.

I have really good experience with free package Syrup for Maple. It can symboliclly evaluate all currents and voltages in circuit (ac, dc and tran analysis), from enetered spice netlist. It was enough for my problems. Here is download and examples link:
http://adept.maplesoft.com/powertools/syrup/Syrup.shtml
http://adept.maplesoft.com/powertools/syrup/html/Syrup_examples.html
For more complex circuits, solutions can become too large, and some sort of simplifications should be done. For example 1/gm<<rout, which alows 1/gm to be neglected in the sum. Also user could specify such conditions for some other circuit parameters. ISAAC is comercial package for mathematica that has such functions, but in my opinion too expensive, because it is not stand alone program...
Tina Pro has schematic capture and is also interesting.
Here are some symbolic simulators for which I have heard, but not used:
ASAP, SYNAP, SAPEC, SSPICE, SCYMBAL, SCAPP, GASCAP
For more information, you can read chapter 32 of the book Trade offs in analog circuit design:

| another problem is when calculating the poles and zeros in symbolic form, it is impossible if the order is larger than 4. and what is the best approximation method? any publication on that?

| in matlab use 'pzmap' function to plot all zeros and poles in s plan

XFUNC is very good and easy to use DOS symbolic simulator.
Try [url]http://www.mirrorservice.org/sites/ftp.simtel.net/pub/simtelnet/msdos/electrcl/
The file is Xfunc22.zip[/url]

| Try Maxima (sourceforge.net). It's free software for *nix & windows. And it's most powerfull and forebear for maple, matlab and other symb. simulators.

i think maple is a good tools for analog circuit analysis.
maple + matlab maybe perfect

try electronic work bench........thebest......it has storage ocilloscope...14 channel analyzer.....and many i think 14 virtual instruments......if u have full version.......
