I work on my thesis and I want to design multiplier wallace tree 16 bit with 4:2,6:2 compressor, but I can not write VHDL code very well. please help on my problem.
Hello Your problem is very hard and is microsoft problem,after earth warming and ozon problems, it’s the the third problem in the world. Your problem is my problem This problem is specially for semnan university and Dr.keshavarzi student’s If you solve this problem please call me Kholase in hame ro goftim ke agar be javab residin khabar bedin.

You can find a generic implementation of a wallace tree multiplier here: http://www.openhdl.com/vhdl/655-vhdl-component-wallace-tree-multiplier-generic.html
This implementation uses a small set of recursive functions to identify the number of applicable bits at a given layer. The main code then maximizes the number of 3:2 compressors (full adders) followed by 2:2 compressors (half adders) and then wires.
The final partial sums are fed into a generic Brent-Kung adder (a type of carry tree adder like other carry look-ahead adders including the Kogge-Stone adder).
