The Student's Guide to VHDL is a condensed edition of The Designer's Guide to VHDL, the most widely used textbook on VHDL for digital system modeling. The Student's Guide is targeted as a supplemental reference book for Computer Organization and Digital Design courses. Since publication of the first edition of The Student's Guide, the IEEE VHDL and related standards have been revised. The Designer's Guide has been revised to reflect the changes, so it is appropriate that The Student's Guide also be revised. In The Student's Guide to VHDL, 2nd Edition (SG2E), we plan to include a design case study illustrating an FPGA-based design flow. The aim is to show how VHDL modelling fits into a design flow, starting from high-level design and proceeding through detailed design and verification, synthesis, FPGA place and route, and final timing verification. Inclusion of the case study will better serve the educational market.
