Resumen
Complex embedded systems can no longer be effectively designed without consideration of the interaction of hardware and software domains. Current hardware description languages, such as VHDL and Verilog HDL focus on physical or register transfer logic levels and do not provide enough abstraction for complex system level designs. Architectural description languages provide higher levels of abstractionfocusing on the structural aspects, such as abstract components and their interactions. This work describes a new environment to specify and capture architectural design expertise of embedded systems. The architecture description is based on the composition of hardware and software components with the addition of an interface between them. Nonfunctional constraints for components and their interfaces can also be modeled and verified. The ideas discussed in this work have been implemented in a tool. This tool enables the description of an embedded system through a specific language, LACCES. It can also allow the behavioral simulation and the non-functional verification of the hardware and software components.
