Abstract
Hierarchy plays a significant role in the design of digital and analog circuits. At each level of the hierarchy it becomes essential to evaluate if a sub-block design is feasible and if so which design style is the best candidate for the particular problem. This paper proposes a general methodology for evaluating the feasibility and the performance of sub-blocks at all levels of the hierarchy. A modified simplicial approximation technique is used to generate the feasibility macromodel and a layered volume-slicing methodology with radial basis functions is used to generate the performance macromodel. However, due to lack of space, only details of the performance macromodeling techniques are included. Macromodels are developed and verified for analog blocks at three different levels of hierarchy (current mirror, opamp, and A/D converter). 1. INTRODUCTION As feature sizes shrink even further, an increasing percentage of IC's will have analog circuit designs in them, stressing the need f...
