Default Simulation after board Layout.

We had been seeing lot of different simulators available for schematics.

I was wondering If there is any that runs the simulation even after the board is completed. so that you know if the layout is good enough for the schematic.
In other words a tool which considers stray inductance ,capacitance and noise radiation of the designed board.

There are such tools available, but they are incredibly expensive. What you're thinking of is called a "field solver" that can consider either 2 or 3 dimensions and solve Maxwell's equations for the physical design. See Cadence or Agilent ADS for example.

Thanks for the reply.

I checked, the cost, they are really high. but thanks for updating my knowledge

I use the Zuken Signal Integrity software, these simulations are mainly for high speed designs. What do you want to simulate?
Even today simulation is not as widespread as it could be, this is due to cost of software and time restraints as well as other factors. Time and manpower required to perform the simulations become a factor, as doing simulations involving multiple line cross talk take ages!!!
If you are doing digital layout becoming au fait with layout techniques is the best at the start, and for a lot of designs following good practice guidelines will often suffice.
I have plenty of info on simulation and digital design if you want any more info.
