Hi, I'm a Verilog HDL and VHDL expert with 15+ and 13+ years experience, respectively. I have implemented more than 125 designs for third parties/clients including MSF/DCF77 decoder, FFT, RISC processors, ASIPs for image/video processing, FSMs/FSMDs for various control and data computation tasks. I have the Pong P. Chu book at my personal library (your excerpt is from the VHDL version), and have all three of the following boards: Spartan 3, 3E and 3AN starter kits. Overall, more than 40 designs implemented and verified on these boards.
