Problems solved by technology

[0004] The problem is that as the system LSI becomes more complex and larger in size, it is necessary to prepare more of these functional models
As a result, this may destroy any benefit of co-design as the added processing steps offset or even outweigh the stated benefit

Abstract

A simulator apparatus comprises a simulator model including a functional model for CPU constituting a system to be simulated and a simulator model including a functional model for hardware to be connected to buses linked to the CPU. The respective simulator models include plural types of interfaces. The plural types of the interfaces enable plural types of simulators for different uses to access the functional models. The simulator apparatus further comprises a simulator controlling device for selecting any of the plural types of the interfaces and accessing the respective functional models via the selected interfaces.

Description

technical field [0001] The present invention relates to a simulation technique for large-scale integration (LSI), and more particularly, to an improvement in a technique for efficiently verifying hardware, software, and systems in an upstream design stage of a chip-level system structure. Background technique [0002] In recent years, there has been an increasing demand for integrated circuits of monolithic structure, miniaturization, weight reduction, energy saving, and cost reduction. This trend is especially evident in the field of digital IT home appliances. In response to such demands, the semiconductor chip manufacturing industry has shifted its attention to system LSIs. [0003] If the system is divided into hardware and software so that the hardware and software are developed sequentially, development takes longer. Therefore, so-called "co-design" in which hardware and software are jointly developed at the same time is increasingly employed. In the case of co-desi...
