Design space exploration is the process of analyzing several functionally equivalent alternatives to determine the most suitable one. A fundamental question is whether an implementation is consistent with the high-level specification or whether two implementations are “equivalent.” The synchronous assumption has made it possible to develop efficient procedures for establishing functional equiva...

The design space exploration (DSE) subsystem of a design automation tool is responsible for early identification of interesting zones of the design space. Evaluation of the exploration strategy used in a tool is extremely difficult because there is not enough information about either the design space or the actual cost function. This paper describes a software environment for quantitative evalu...

Communication design for SoCs poses the unique challenges in order to cover a wide range of architectures while offering new opportunities for optimizations based on the application specific nature of system designs. In this report, we propose automatic generation of communication architecture from communication link model where system components communicate through logical links of network arc...

| This paper describes an exact solution methodology, implemented in Rensselaer's Voyager design space exploration system, for solving the scheduling problem in a 3dimensional (3D) design space: the usual 2D design space (which trades o area and schedule length), plus a third dimension representing clock length. Unlike design space exploration methodologies which rely on bounds or estimates, th...

In this paper we propose an original and fast design space exploration method targeting reconfigurable architectures. This method takes place during the first steps of a design flow that works at the algorithmic level. It uses as input a high level specification of the application and is based on a functional model to describe the architectures to compare. This paper describes the projection st...

As design problems become more complex and design lead time more pressing, designers need effective support tools to expand their design space exploration. In this paper, a hierarchical coevolutionary approach is proposed to support designers by automatically generating design concepts based on the designers’ inputs. The approach adopts a zigzag design process in which function structures and t...

Design space exploration is the process of analyzing several functionally equivalent alternatives to determine the most suitable one. The synchronous assumption has made it possible to develop e cient procedures for establishing functional equivalence betw een di erent implementations in the domain of synchronous circuits as well as in the domain of sync hronous reactive systems. We extend this...

The Sesame system-level simulation framework targets efficient design space exploration of embedded multimedia systems. Even despite Sesame’s efficiency, it would fail to explore large parts of the design space simply because system-level simulation is too slow for this. Therefore, Sesame uses analytical performance models to provide steering to the system-level simulation, guiding it toward pr...

1. We propose a technique for test scheduling and design of test bus infrastructure where test application time and test bus length and width are minimized while constraints on power consumption and test resources are considered. Our approach is suitable for repeated use in the design space exploration process due to its low computational cost. For the final design, we use simulated annealing t...

This chapter focuses on resource management techniques for performance or energy optimization in multi-/many-core systems. First, it gives a comprehensive overview about resource management in a broad perspective. Secondly, it discusses the possible optimization goals and constraints of resource management techniques: computational performance, power consumption, energy consumption, and tempera...
