TRANSFORMAÇÃO DE FSM DESCRITAS EM STATEFLOW PARA VHDL

Abstract

Nowadays, the tool of visual modeling is veryused in engineering domain. In this work is presented amethodology and a translation tool called SF2TAB. Itsobjective is transition diagram translation of finite statemachine described through Stateflow-Matlab/Simulink for astandard file used by the synthesis tool called TAB2VHDL.The SF2TAB, developed on C language, interprets asubgroup from many available resources in Stateflow fordescription and analysis of FSM. To evaluate the developedtool, some finite state machines describe plants of industrialcontrol systems are being projected. The functions ofexcitations and generated exit are described through VHDLlanguage, that allows configure in FPGA the FSM modeledusing the Stateflow. The simulations proved that SF2TAB haspotential to be used as a tool to help in the development ofelectronic control systems with FPGA device in disciplinessuch as project of digital systems.
