Problems solved by technology

[0006] However, when, for example, the structure of the CPU model is different between two simulators, the interface of the existing hardware model compatible with the interface of one CPU model is not compatible with the interface of the other CPU model, so that it is necessary to design a new hardware model to Make the interface of the hardware model compatible with the interface of the CPU model
As a result, product development cost and development time cannot be reduced, the quality of the hardware model cannot be maintained, and resources cannot be effectively used
[0007] Patent Document 1 does not disclose or suggest a mechanism for eliminating incompatibility between interfaces caused when the structures of the simulators are different as described above

Embodiment Construction

[0025] Embodiments of the present invention will be described with reference to the accompanying drawings. figure 1 The structure of the simulator according to the present embodiment is shown.

[0026] The simulator 50 includes a CPU model part 10 , a peripheral hardware model part 20 , a bridge 1 and a storage part 30 , wherein the bridge 1 is used to coordinate mutual access between the peripheral hardware model part 20 and the CPU model part 10 .

[0027] The CPU model section 10 includes CPU models (modules). Each CPU model has at least a CPU function, and also has an OS function running on the CPU, and an application function running on the OS.

[0028] In this embodiment, the CPU model 100A consists of a CPU configured by software ( figure 1 Expressed as "CPU(SW)"), the CPU functions and the OS and applications running on the CPU are simulated. The structure of the CPU model 100B is realized by an OS simulator (software) including CPU functions. The CPU model 100C co...

Abstract

An object of the present invention is to provide a bridge program, bridge and a simulator; said bridge program is capable of achieving common use of the interface between a plurality of modules having different configurations and a hardware model obtained by modeling hardware with software. A bridge program allows a computer to execute: an acquisition step that acquires an operation instruction issued from the module to hardware model; a conversion step that converts the interface of the module into a common interface corresponding to the hardware model; and a discrimination step that acquires the operation instruction acquired by the acquisition step via the common interface into which the interface of the module is converted by the conversion step, discriminates to which hardware model the operation instruction is issued, and outputs the operation instruction to the discriminated hardware model.

Description

technical field [0001] The present invention relates to a bridge program, a bridge method, and a simulator for executing the bridge program, wherein the bridge program and the bridge method convert specific interfaces of a plurality of modules having different structures into a common interface so as to realize the modules Links to hardware models. Background technique [0002] In the development process of a product composed of a CPU and peripheral hardware, a simulator is used to verify the operation of some or all of the components included in the product. [0003] In most cases, the emulator configuration is different depending on the target product to be verified. In one simulator, a CPU model for simulating the functions of the CPU is realized by hardware, and a hardware model for simulating the functions of peripheral hardware different from the hardware modeled by the CPU model is realized by software on the computer. In another simulator, both the CPU model and th...
