A practical primer for the student and practicing engineer already familiar with the basics of digital design, the reference develops a working grasp of the VHLD hardware description language step-by-step using easy-to-understand examples. Starting with a simple but workable design sample, increasingly more complex fundamentals of the language are introduced until all core features of VHDL are brought to light. Included in the coverage are state machines, modular design, FPGA-based memories, clock management, specialized I/O, and an introduction to techniques of simulation. The goal is to...
