... change. As such, the material in this book focuses on the core aspects of the Verilog-A language as presented in the LRM and the work within the OVI Verilog-A Technical Subcommittee. The goal of this ... book is to provide the designer a brief introduction into the methodol- ogies and uses of analog behavioral modeling with the Verilog-A language. In doing so...

... design. The behavioral description is done in a programmatic fashion in the Verilog-A lan- guage within the analog statement or block of the module. The analog block encapsulates the behavioral ... Because of mathematical and other properties associated with analog opera- tors, there are special considerations in their usage. These and other issues associated with...
