Proposta de uma infraestrutura de geração e avaliação para redes intrachip Hermes-G

Abstract

Advances related to integrated circuit manufactring technologies push the complexity and the number of functionalities in electronic products. The literature points out that in 2015 behavioral design will demand 50% of the whole design effort, what indicates a major need for developing circuit design automation tools. Besides that, the design of current circuits employs the synchronous design paradigm prioritarily. However this design paradigma jointly with the increase of complexity imposes relevant restriction with regard to energy consumption and power dissipation design constraints. This works presents an alternative to some of the cited problems, proposing an environment for the generation and evaluation of intrachip networks. These networks allow interconnect processing modules operating at different operating frequencies, as well as help to guarantee the fulfillment of temporal restrictions temporais imposed by the traffic requirements of such modules. During the network generation step, the proposed environment allows selecting the network characteristiscs at design time, including individual router operating frequencies. Besides network generation, the environment also enables evaluating temporal contraints for several distinct traffic models, supporting the parameterized generation of traffic to exercise the network. This characteristic offer new alternatives to reduce the design effort of intrachip network for electronic systems still in the early phases of system specification. This occurs because the environment enables the visualization of the network behavior, demonstrating if this fulfills or not the expected requirements for some give traffic scenario.
