Integrated System Modeling

The design and verification of analog, mixed-signal and mixed-technology systems can be difficult and complex. The process of top-down design for these types of systems is less straightforward than for digital systems. In this chapter we discuss how to use subsystem models with different abstraction levels to answer system-level questions, make system-level trade-offs, verify system performance and discover problematic interactions. We focus on the design process and the role played by VHDL-AMS models.

25.1 Top-down Design

Top-down design methodologies have had a profound impact on digital system design. They allow us to quickly and efficiently specify, design, synthesize and verify designs ready ...
