This paper deals with the creation of the tool for chip design in UML. The intention of this work is to present the news in the UML language version 2.0, that can be possibly used for modeling of embedded systems. Furthermore, it deals with the possibility and method of modeling in the Eclipse environment and it focuses on the Eclipse Modeling Framework. This work explains the principle of developing of graphical editors based on GMF used fully by developing tool. Finally, it discusses the chosen solution.

O tratamento de exce??es ? uma das t?cnicas mais utilizadas para a constru??o de sistemas de software robustos. A pol?tica de tratamento de exce??es ? o conjunto de regras que define como as exce??es devem ser manuseadas. Por?m, na maioria dos casos, essa pol?tica n?o est? definida de forma expl?cita, sendo um desafio para o desenvolvedor criar o c?digo de tratamento de exce??es. Este trabalho prop?e uma ferramenta em formato de plug-in do Eclipse, denominada ExceptionPolicyExpert, que tem o objetivo de orientar o desenvolvedor na implementa??o desse tipo de c?digo de forma a atender uma pol?tica previamente definida. Esta ferramenta analisa o c?digo fonte e verifica se h? alguma viola??o ? pol?tica de tratamento de exce??es, alertando o desenvolvedor para n?o conformidade, caso exista. Para auxiliar o levantamento dos requisitos da ferramenta, foi realizado um estudo explorat?rio com desenvolvedores, utilizando t?cnicas de Grounded Theory, que buscou entender quais eram os principais desafios deles no momento da implementa??o do c?digo de tratamento de exce??es. O estudo mostrou que a maioria deles n?o recebem orienta??es a respeito da pol?tica de tratamento de exce??es e nem tem acesso ? pol?tica de tratamento de exce??es a ser seguida. Consequentemente, muitas vezes lidam com esse c?digo de forma indevida. Dessa forma, foi proposta uma ferramenta que visa trazer informa??es sobre a pol?tica de tratamento de exce??es para a IDE, de forma que auxilie o desenvolvedor na implementa??o do c?digo excepcional sem violar a pol?tica. A avalia??o da ferramenta mostrou que ela auxilia o desenvolvedor a tomar decis?es no momento da implementa??o do c?digo de tratamento de exce??es. / As our society becomes more and more dependent of software systems the demand robustness requirements increases. The exception handling mechanism is one of the most used techniques to enable the development of robust software systems develop. The exception handling policy comprises the set of rules that specify how exceptions should be thrown and handled inside a system. But usually the policy is not explicitly defined. As a consequence, it becomes a challenge for developers to create the exception handling code according to it. This work proposes an Eclipse plug-in, called ExceptionPolicyExpert, to guide the developer on how to implement this kind of code by checking policy violations and providing recommendations to developers concerning how to exceptions should be handled and signaled. In order to support the creation of such tool, we performed an exploratory study, using Grounded Theory techniques, to understand which are the main challenges that the developers have during the implementation of the exception handling code. This study showed that most of the developers did not receive any instructions regarding the exception handling policy and they often handle exceptions in a wrong way. Therefore, the proposed tool aims to provide information to developer regarding the exception handling policy integrated to the IDE - helping him/her to develop exception handling code and preventing policy violations. The tool evaluation showed that the tool helps the developer to make decisions when implementing the exception handling code.
