Description and Objectives

• Validation methods for software models of electrical components with the objective of expanding the use of bit-level software simulations from software development to spacecraft design
• Rapid prototyping of spacecraft design and function through software simulation and models
• High fidelity software models of electronic components
• Library of validated, reusable software models

Hardware Model Development Process

Technical Approach

• Investigate capabilities and limitations of WindRiver Simics Simulation Toolset and of NASA IV&V ITC software model of JWST spacecraft
• Identify and implement model refinements for use case mission, e.g., JWST

Main Innovation(s)

• High fidelity embedded system environment
• Model validation process
• Reconfigurable and reusable SW models for spacecraft simulation and architecture prototyping
• Reduce space missions cost and risk due to early SW development on spacecraft simulation

Infusion Potential

• Most flight projects
