RASSP Integrated Systems Tool Appnote

Abstract

The goal of the DARPA/Tri-Service-sponsored Rapid Prototyping of Application Specific Signal Processors (RASSP) program is to reduce development and manufacturing time and cost of signal processors by a factor of four. Lockheed Martin's Advanced Technology Laboratories (ATL) RASSP team has developed an integrated systems engineering tool set which forms the basis for a concurrent engineering design environment. This design environment, which consists of Ascent Logic's RDD-100, Lockheed Martin PRICE Systems parametric cost estimation models, and Management Sciences Inc. RAM-ILS tools, provides the integrated product development team with cost and reliability estimation data within a systems engineering toolset. The concurrent engineering design environment is described and an example is provided which demonstrates the value of the tool integration within the design environment. This design environment enables the integrated product development team to estimate the life-cycle costs and reliability early in the design process.

Purpose

Systems engineering decisions early in a project significantly impact schedule and cost. Decisions are typically based on the impact to the current phase of a project, rather than the project's overall life cycle.To help the integrated product development team (IPDT) make these trade-off decisions, the ATL RASSP team developed a concurrent engineering environment consisting of Ascent Logic Corporation', (ALC) RDD-100 tool with Lockheed Martin PRICE Systems' parametric cost estimation models and Management Sciences Inc. (MSI) RAM-ILS tool set. This application note will help you learn more about using these tools in this concurrent engineering environment to provide design, cost, reliability, availability, and maintainability support to the IPDT.
