Hello,
Please can u guide me which is the best simulation tool to simulate dc dc converters and validate a design before a board stage?
thank you
 

That would depend a lot on your personal values. Cost?
Speed? Accuracy? Availability of decent models for the
parts you want to use?

LTSpice wins on many of these, provided you are using
one of the controllers for which it has the behavioral
models - you can get real fast solutions, if so. Otherwise
it's just another free SPICE with a nice schematic capture
and waveform tools. Which is a pretty limited club.
 
LT Spice and PSIM are the best solution. LT Spice is open source and PSIM is limited version.
 

I don't believe LTSpice is open source. It is a freely
available binary distribution with libraries but Linear
Technology remains its owner and restricts its use
(on paper - who bothers?). There are active user
groups with large circuit archives which can help a
new user out a lot.
