Abstract :
In a top-down design methodology, design tasks are divided into simpler sub-tasks across levels of hierarchy and abstraction as an effective divide-and-conquer technique. For every task, tolerances are defined on all performance characteristics to take into account parasitics, mismatches and other nondeterministic process parameter variations. Constraint transformation is a process used to translate performance specifications into sub-task requirements. This paper introduces the problem of constraint transformation and describes some formal solutions for analog circuit applications. Examples illustrate the methodology and show the suitability of this approach for industrial-strength applications
