Dear frnd ,
can any one help me out in synthesizing a ckt using only nand nor and not gate. i am using desing
vision tool for logic synthesis.

Entire circuits can be synthesized using just NAND gates OR just NOR gates. For simple circuits thats OK, but its easier and more efficient to define your circuits in some HDL and let a computer handle anything more complex than a handful of gates.

If you must synthesize in just NAND, know De Morgans backwards. The pic may be of help.

Simply put
Take any input and negate it you have a NOT
negate it Again you have a BUFFER

if you take a NAND and negate inputs you get an OR.
if you take a OR and negate outputs you get an NOR.
if you take a NOR and negate inputs you get an AND.
if you take a AND and negate outputs you get an NAND.

and in reverse.
