books on altera FPGA

Hi,

i recently graduated from electrical engineering.

i am very much new to altera and VHDL.

i bought the DE2 board, read its tutorials and watched some of the on-line tutorials.

i was wondering if one might suggest a book specific for altera. one with practicle examples that both teach on good VHDL programming and good design techniques. the ideal book will be up-to-date, with examples i can implement and modify by my self and theory that is buckedup by practicle examples.

if such a book is not available then two or even three books will also be good.

my main goal is to work in the field.

Thanks and Regards, Ran.
