Advanced Digital Logic with VHDL

Introduces the use of the industry-standard hardware description language VHDL into the digital design process. Following a review of the basic concepts of both logic design and VHDL, the author incorporates more coverage of VHDL topics as needed, with advanced topics covered in Chapter Eight. Rather than simply teach VHDL as a programming language, this book emphasizes the practical use of VHDL in the digital design process. For example, in Chapter Nine, the author develops VHDL models for a RAM memory and a microprocessor bus interface; then uses a VHDL simulation to verify that timing specifications for the interface between the memory and microprocessor bus are satisfied. The book also covers the use of CAD tools to synthesize digital logic from a VHDL description, and stresses the use of programmable logic devices including programmable gate arrays.
