In the context of Software Product Lines (SPL), it is important to have this support, which allows the correspondence between this two activities, with management of variability. In order to address this issue, this paper presents a process of bidirectional mapping, defining transformation rules between elements of a goaloriented requirements model (described in PL-AOVgraph) and elements of an architectural description (defined in PL-AspectualACME). These mapping rules are evaluated using a case study: the GingaForAll LPS. To automate this transformation, we developed the MaRiPLA tool (Mapping Requirements to Product Line Architecture), through MDD techniques (Modeldriven Development), including Atlas Transformation Language (ATL) with specification of Ecore metamodels jointly with Xtext , a DSL definition framework, and Acceleo, a code generation tool, in Eclipse environment. Finally, the generated models are evaluated based on quality attributes such as variability, derivability, reusability, correctness, traceability, completeness, evolvability and maintainability, extracted from the CAF? Quality Model / O rastreamento entre modelos das atividades de requisitos e arquitetura ? uma estrat?gia que busca evitar a perda de informa??es, reduzindo o gap entre essas duas atividades iniciais do ciclo de vida do software. No contexto das Linhas de Produto de Software (LPS), ? importante que haja um suporte a esse rastreamento, que permita a correspond?ncia entre as duas atividades, com um gerenciamento satisfat?rio das variabilidades. Buscando atender a essa quest?o, este trabalho apresenta um processo de mapeamento bi-direcional, definindo regras de transforma??o entre elementos de modelo de requisitos orientado a objetivos (descrito em PL-AOVgraph) e elementos de descri??o arquitetural (definida em PL-AspectualACME). Essas regras de mapeamento s?o avaliadas em um estudo de caso: a LPS Ginga ForAll. Para automatizar essa transforma??o, implementamos a ferramenta MaRiPLA (Mapping Requirements to Product Line Architecture), atrav?s de t?cnicas do desenvolvimento dirigido a modelos (Model-driven Development MDD), incluindo a linguagem de transforma??es entre modelos Atlas Transformation Language (ATL) com especifica??o de metamodelos do tipo Ecore em conjunto com os frameworks Xtext, de defini??o DSL, e Acceleo, de gera??o de c?digo, em ambiente Eclipse. Por fim, os modelos gerados s?o avaliados, com base em atributos de qualidade como variabilidade, derivabilidade, reusabilidade, corretude, rastreabilidade, completude, evolutibilidade e manutenibilidade, extra?dos do Modelo de Qualidade CAF?
