New product features require ever increasing software complexity. In turn, modern hardware comprises multiple processors and numerous bus interconnections. Increased development risk and cost makes complex system development appear unmanageable and open-ended. simpleXecutive Methodology's focuses on getting the system design right, before writing a single line of code, by modeling system performance. Our patented SIMPLEX modeling tools have delivered successful results on multiple complex systems, ranging from Boeing 787 on-board avionics, to medical diagnostic devices, to classified Star Wars programs. Our SIMPLEX modeling tools give the system engineer and designer the ability to evaluate, modify and enhance their system design for maximum performance, while it is still on the drawing board. Throughout the modeling process, SIMPLEX automatically validates data integrity at a system level. Our engineering tools address the design challenges of development and integration and can supplement your existing development tools.Our engineering modeling tools apply at any phase of a project, whether creating a new project or integrating new features to an existing system.
