Interface Constraints

Abstract

Timing constraints can be used to represent interfaces with external processes or local constraints between pairs or groups of code operations. Five categories of timing constraints are analyzed below. We will assume timing constraints are given in terms of the clock period. Otherwise we can convert using the following: we use for minimum timing constraints and for maximum timing constraints, where t _c is the period of the clock (equal to one cstep) and t is the real time constraint given by the specification. We will investigate the following types of timing constraints for architectural synthesis:

• Fixed Timing

• Minimum Timing

• Maximum Timing

• Unknown Timing

• Special Timing Constraints
