  • Patent number: 10802852
    Abstract: According to an embodiment, a system and method are provided for supporting interactive debugging of embedded software (ESW) on a simulation platform. A processor model within the simulated system will support a register and memory tracing sub-module. Simulator and emulator breakpoints will be used with the modeled objects within the tracing sub-module. For example, a simulator breakpoint may be set for the task or function that buffers the trace information so it can be written to a file. A database of register and memory values which represent the complete history of register and memory value changes during a simulation can be created from trace information and can be accessed to non-intrusively obtain any processor register or memory value during simulation. The processor register and memory values of the database can also be accessed to symbolically show the behavior of ESW concurrently with hardware behavior in the simulation.

  • Patent number: 8296119
    Abstract: Method, system, and computer program product for saving and restarting discrete event simulations are provided. A discrete event simulation of a scenario is performed via a process executing on a system. The process includes one or more application threads. A checkpoint of the process is created at a point in time when a command to save the discrete event simulation of the scenario is received. The checkpoint includes data elements of the process and the one or more application threads of the process that are stored in components of the system at the point in time. These data elements reflect a state of the process and the one or more application threads of the process at the point in time. The checkpoint is saved to one or more files in the system that are usable to later restart the discrete event simulation of the scenario from the point in time.
