Abstract

This chapter investigates the applicability of discrete event hardware description languages (HDLs), in general, and VHDL, in particular, to the design and documentation of analog electronic systems. The study focuses on the types of analog systems that can be modeled using IEEE 1076–1993 VHDL, without extensions to the language. To that end, data-sampled analog systems are defined and two subclasses of data-sampled analog systems are examined: network-independent and networkdependent behaviors. With respect to network-independent data-sampled analog systems, examples are presented of basic transformational descriptions, e.g., an operational amplifier, and more advanced discrete-convolution based descriptions, e.g., a lowpass filter. With respect to network-dependent data-sampled analog systems, examples of modeling loading effects and utilizing two-port network theory are presented. This work provides a perspective on the capabilities and limitations of discrete event hardware description languages in modeling analog or continuous event behavior. The classes of analog systems investigated illustrate present modeling technology and suggest directions for future applications of emerging analog modeling languages.
