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 behavioral description is done in a programmatic fashion in the Verilog-A lan-

encapsulates the behavioral ... Because of mathematical and other properties associated with analog opera-
