I am looking for a circuit simulation software, so that I can make a circuit using ds89c430 microcontroller, simulate/check and then purchase the parts and make a kit.
Can you please let me know, which circuit simulation software is good, and supports 8051 microcontrollers.
Better if open source / free circuit simulation software.

supports 8051 microcontrollers.
Free instruction set simulators are available but they won't exactly model specific chips.
A software simulator that correctly and completely models the cycle-by-cycle behavior of a particular processor, its memory layout, and its peripherals isn't going to be cheap. Keil seems to have one for the DS9C430 but they don't give a price online, just a request for a quote, so stand by for $$$$.
A much less expensive alternative loader/debugger is NoICE
But, IMHO, simulators aren't all that useful. Better to develop on the target silicon and wiggle a bit or two, if required.

If you want a simulator that'll simulate the processor with its software, I'm nearly certain that you're out of luck -- if such a thing exists it'll be from Mentor or some other high-zoot place, and it'll cost $50,000 a seat.
Of course, it'll be nice to be surprised on this one.

And if the microprocessor is going to be tightly integrated with hardware, (i.e., it'll generate a PWM for a switching amplifier or something), then implement a simplified algorithm in your flavor of SPICE's logic, and see how the circuit reacts.

We use Proteus VSM which does support 8051. But we use it for PIC family only.

Look for sim8051.exe by Steve Nolan, circa 2000, free.
It works with 8051 code and I have used it to check all my programs. Really good.
Google for it. Otherwise I can post a copy Maybe here:

good,

Not too shabby. However it only seems to simulate the digital/uC portion of a design and does not have a connection to SPICE.

That link only to the VSM (uC sim) part of the package. There is full circuit simulation built into the suite. The VSM is not used by all and is a fairly expensive add-in.
