Abstract

In this paper, we propose a design exploration framework which consider impreciseness in design specification. In high-level synthesis, imprecise information is often encountered. Two kinds of impreciseness are considered here: imprecise characteristics of functional units and imprecise design constraints. The proposed design exploration framework is based on efficient scheduling algorithm which considers impreciseness, Register-Constrained Inclusion Scheduling. We demonstrate the effectiveness of our framework by exploring a design solution for a well-known benchmark, Voltera filter. The selected solution meets the acceptability criteria while minimizing the total number of registers.
