A simulation apparatus is disclosed, including a group switching part. The group switching part refers to a priority management table, which manages priority information of priorities to assign a CPU for multiple groups of tasks stored in a storage area, and changes the priorities of the multiple groups of tasks, when an event occurs to activate a task to be executed in verifying of software by using a simulation.

Simulation apparatus, method, and computer-readable recording medium

A simulation apparatus is disclosed, including a hardware simulator and a CPU model. The hardware simulator activates one or more logical hardware models for verifying embedded software. The CPU model is one of the one or more logical hardware models which imitates a CPU which executes the embedded software, and to trigger the embedded software to operate without synchronization for each of instructions.

Simulation apparatus, computer-readable recording medium, and method

A simulation program stored in a computer readable recording medium to execute a simulation of first and second simulation objects is provided. The simulation program includes a storage that stores one of an initial state, a read waiting state and a write waiting state for a channel used for data transfer between the first and second simulation objects; a receiver that receives a read request from the first simulation object to the second simulation object through the channel; a judgment unit which, upon reception of the read request, judges whether a state corresponding to the channel is the read waiting state; a transmitter which transmits data corresponding to the channel stored in a storage area to the first simulation object when judging to be the read waiting state; and a changer that changes the state to the initial state based on the data transmission.
