Circuit functional reliability simulation based on grid

The functional reliability simulation(FRS) is an advanced integrative simulation and analysis technology in reliability by integrating functional simulation with reliability analysis of system.The architecture and functions and mostly realization methods were discussed,such as failure modeling,virtual failure rejection,simulator integration,failure automatic criterion about FRS.In order to resolve the problems about simulation time and data storage,a new architecture was put forward,which is based on the grid technology,and the related service of simulation,analysis,data management and so on was represented.The grid provides a virtual capability of computing and storage.The new architecture shortens the simulation time and realizes the distributed data storage.The Tyrensgrid circuit functional reliability simulation(TG-CFRS) system was produced based on the idea,which makes the Tyrensgrid as the grid platform and PSpice as the simulation kernel and proves the availability of the new architecture.
