SIMULATION OF MULTIPLIER

I have designed a Multiplier (Frequency Doubler),How will i Simulate it ?I am a beginer So Please answer in detail.

compile all the small modules and compile the top module then simulate the to[p module

You can simulate a frequency multiplier (e.g. frequency doubler) nonlinear behaviour using harmonic balance simulation. Most microwave simulation and analysis programs, such as Agilent Advanced Design System (ADS), Appwave's Microwave Office (MWO) and Eagleware's Genesys has this feature.

We discussed this before. The programs mentioned would do a good job IF there were a good model for a Step recovery diode, which apparently there is not.
