Synthesizable VHDL

[aravind]

I've heard only synthesizable on rtl descriptions can be realized on
hardware.
So how do we write rtl descriptions? What are the do's and dont's while
writing a vhdl code for synthesis?

Do use a synchronous process.
Don't use "wait for".
Do start with some known-good examples.

Aravind,
Besides the wonderful examples by Mike Treseler,
check out some synthesis centric books, like:

RTL Hardware Design Using VHDL: Coding for Efficiency, Portability, and
Scalability
by Pong P. Chu

The website, with code and other collateral is:
http://academic.csuohio.edu/chu_p/rtl/index.html

I'm using this book in an HDL class I'm teaching, and finding it very
useful for synthesis
