How to configure keil. Let say I have ADC pin on 89c51 in simulation. Now how to generate some analog signal on it.
You can manually enter a voltage in the peripherals view, when using the simulator.
I currently have a bug report open for the XC878, because the simulator doesn't execute the ADC interrupts, but because you're on a different platform I don't expect you'll have similar problems.
The uVision Manual provides a worked example on this very subject...
Can you point the link. Also is there downloadable version of manual
Manuals are at http://www.keil.com/c51/man/c51.htm
Why?
Even when someone does give you a direct link to specifically answer your question, you don't bother following it: http://www.keil.com/forum/21775/
"is there downloadable version of manual"
Oh, come on - are you making any effort here at all??
