Embedded Systems Requirements Verification Using HiLeS Designer

One of the issues related to systems design is the early verification in first design steps: system specifications verification. Nowadays, it is common to use text-based specifications to begin a system design. However, these specifications cannot be verified until a software model is made. In this work, we show how can we use HiLeS Designer to model and verify, formally and by simulation an embedded system specification. This tool makes easier to build the model, using graphical concepts which are familiar to designers. It also helps to verify formally the structure and some logical behavior, and by simulation, it is possible to verify the consistence of the embedded system specification. We model and verify System Display Selector Requirements applying HiLeS Designer.
