I want to fix a code in vhdl.i have to give the numbers from 0-255 as input and i want to take in outout the nymbers in hex system in 2 seven segment display.

here you can find display patterns for the digits 0 to f used in HEX representation http://en.wikipedia.org/wiki/Seven-segment_display_character_representations

I'm afraid your question is incomplete. So I'm now guessing: - I believe you have an eight bits wide unsigned input vector. - I also estimate that your seven segment displays are connected to your FPGA 1:1 and thus do not need to be multiplexed. If I'm right with both estimations, the simplest way for you to do it is the following: - In your thoughts, split up your eight bits wide vector into two four bits wide vectors, each of them serving one display. - For each four-bit-vector, instantiate a truth table converting all input value patterns possible (0..15) into their correct representations on your display. I suppose you're a VHDL beginner. Here's a good tutorial: http://www.seas.upenn.edu/~ese171/vhdl/vhdl_primer.html The truth tables could be implemented with a SELECT or a CASE statement, for example.
