Development strategies for durable hardware language descriptions of analog and mixed signal circuits

VHDL-AMS, or VHSIC hardware description language - analog and mixed signal extensions is being supported in a variety of design automation tools for circuit design. Although there are a number of published examples on the use of VHDL-AMS for modeling of mixed signal circuits, it is still not clear what are examples of "best practice" methods. This paper discusses research efforts to identify analog macros, or descriptions that can be reused by other designers that are possibly targeting different fabrication processes.
