hi

i want to implement hardware of 16 bit Microcontroller using vhdl code
can anyone tell me what is basics steps to design microcontroller
thanks............

 

Are you familiar with VHDL ? If not, you should first learn to use it for designing simple digital circuits.

Here is an introduction to VHDL:

www.freerangefactory.org/dl/free_range_vhdl.pdf

Chapter 12 shows the VHDL code for some simple circuits.

 

You could give opencores.org a try.

They have numerous soft cores to download to use as learning tools or a base for further development.
