Networking and telecommunication OEMs are at the forefront of design complexity. A network element can contain hundreds of thousands or even millions of source lines and employ hundreds of software tasks, all of which contend for a finite amount of memory and CPU time. To build these massive software systems in the least possible time, OEMs typically opt for parallel development, dividing the work among multiple project teams. In many cases, resource-contention problems tend to emerge and do so only during integration and verification testing, when the cost and schedule impact of software recoding is at its highest. This white paper explains how to avoid weeks or months of corrective actions resulting in increased costs and negating the time-to-market advantages of parallel development.
