High-level design of analog systems is an open area that needs to be a
ddressed with the emerging trend of integrating mixed analog-digital s
ystems. Design methods compatible across the analog-digital boundaries
would expedite the design process, and in this paper we address analo
g high-level design issues. An approach for systems-level synthesis of
a class of analog systems is presented. A behavioral level for the an
alog domain is characterized in terms of state equations and transfer
functions in the continuous and discrete domains. State-space represen
tations are generated from transfer function specifications that exhib
it system level characteristics such as controllability and observabil
ity as well as decoupled and parallel architectures. These state-space
representations are synthesized into behavioral-level, technology-ind
ependent architectures composed of analog functional components. An in
termediate architecture in a circuit implementation technology is synt
hesized from the behavioral architecture. The various algorithmic proc
edures for synthesis are implemented in the program ARCHGEN. Behaviora
l simulation is used for architecture verification and design space ex
ploration.
