The Designer s Guide to Verilog-AMS

The Verilog Hardware Description Language (Verilog-HDL) has long been the most popular language for describing complex digital hardware. It started life as a prop- etary language but was donated by Cadence Design Systems to the design community to serve as the basis of an open standard. That standard was formalized in 1995 by the IEEE in standard 1364-1995. About that same time a group named Analog Verilog International formed with the intent of proposing extensions to Verilog to support analog and mixed-signal simulation. The first fruits of the labor of that group became available in 1996 when the language definition of Verilog-A was released. Verilog-A was not intended to work directly with Verilog-HDL. Rather it was a language with Similar syntax and related semantics that was intended to model analog systems and be compatible with SPICE-class circuit simulation engines. The first implementation of Verilog-A soon followed: a version from Cadence that ran on their Spectre circuit simulator. As more implementations of Verilog-A became available, the group defining the a- log and mixed-signal extensions to Verilog continued their work, releasing the defi- tion of Verilog-AMS in 2000. Verilog-AMS combines both Verilog-HDL and Verilog-A, and adds additional mixed-signal constructs, providing a hardware description language suitable for analog, digital, and mixed-signal systems. Again, Cadence was first to release an implementation of this new language, in a product named AMS Designer that combines their Verilog and Spectre simulation engines.

STRONGThe Designer's Guide to Verilog-AMS/STRONG presents Verilog-AMS, the new analog and mixed-signal extensions to the widely used Verilog hardware description language. BRIt starts by describing a rigorous and proven top-down design methodology. Top-down design is widely seen as the key to being able to design very large and complex mixed-signal circuits and it is enabled by Verilog-AMS. Verilog-A and Verilog-AMS are then introduced without assuming that the reader has a background in behavioral modeling. Finally, it includes a comprehensive reference guide for the language. BRSTRONGThe Designer's Guide to Verilog-AMS/STRONG is extensively cross-referenced and indexed, making it an ideal reference for both Verilog-A and Verilog-AMS. A companion website, www.designers-guide.com, provides electronic copies of all the models used in this book, a library of user-contributed models, a discussion forum, additional documents on simulation and modeling, and other useful material. BRSTRONGThe Designer's Guide to Verilog-AMS/STRONG is written for analog and mixed-signal designers, particularly those designing larger and more complex circuits.
