Abstract : This report addresses the feasibility of and requirements for interfacing two powerful software engineering tools - POD(Performance Oriented Design) and PSL/PSA (Problem Statement Language/Problem Statement Analyzer. POD is a software engineering tool for the life cycle management of system performance. It is a tool which provides a structured machine readable format for representing a system's hardware architecture, software structure and external load demand and, based on this representation, provides the vehicle to calculate system performance values such as response time, throughput and device utilization. PSL/PSA is a computer-aided structured documentation and analysis technique used for analysis and documentation of requirements and preparation of functional specifications. The capability to describe systems in computer processible form is based on the system description language PSL. The ability to record the description in a data base, incrementally modify it, and perform analysis is based on the problem statement analyzer PSA. In considering the feasibility of and requirements for interfacing POD with PSL/PSA, PSL/PSA is assessed in terms of its ability to describe the required POD input specifications. In addition consideration is given to possible PSL/PSA extensions to support POD and an approach for interfacing these tools is determined. (Author)
