This report presents an analysis tool End-to-End Latency Analyzer for ProCom (EELAP) developed to compute different end-to-end latency semantics for multi-rate components of real-time embedded systems. ProCom component technology implements executable reusable real-time components called Runnalbe Virtual Nodes (RVNs) and supports two different communication strategies for inter-RVN communication. The tool is developed to evaluate the two communication strategies for multi-rate server-based components the ProCom component technology. In this report we present a user guide for EELAP. We describe the formulas and corresponding algorithms used to compute end-to-end latency semantics, and response-times of the tasks executing in a two-level hierarchical scheduling framework. Further, we provide a detailed description of APIs.
