An approach for codesign of ERTS based on non-function constraints
Yongxian Jin · 2005
Because of functional and non-functional properties of embedded real-time systems, their development is becoming increasingly complex and difficult. In order to solve this problem, this paper presents a three-step codesign approach based on non-function constraints. The first step develops non-functional constraints using high-level analysis method between different non-functional properties. Then, system functions are generated by use of high-level modeling tools to increase automation. Finally, low-level integration performs relatively conventional codesign to map the functions onto a platform until meeting the non-functional requirements. The method proposed by this paper emphasizes ensuring system timing predictability and amenability to change.
