Abstract

The invention provides a SCE-MI protocol bridge and a simulation system. The protocol bridge comprises a software side module, a hardware side module and a physical channel module; the software side module comprises a software side data generation unit, a software side data receiving unit, a software side data processing unit, a software side routing module, and multiple software side data output channels and software side data input channels based on a SCE-MI protocol, wherein the software side routing module comprises multiple software side nodes and software side adaption nodes; the multiple software side data output channels and software side data input channels based on the SCE-MI protocol are in one-to-one correspondence with multiple software side nodes; and the hardware side module comprises a hardware side routing module, multiple hardware side data output channels and hardware side data input channels based on the SCE-MI protocol, a hardware wide data processing unit, a hardware side data generation unit and a hardware side data receiving unit, wherein the hardware side routing module comprises multiple hardware side nodes and hardware side adaption nodes; furthermore, the structure of the hardware side routing module is the same as that of the software side routing module; and the multiple hardware side data output channels and hardware side data input channels based on the SCE-MI protocol are in one-to-one correspondence with multiple hardware side nodes. By means of the SCE-MI protocol bridge and the simulation system disclosed by the invention, data can be transmitted effectively and orderly.

Description

technical field [0001] The invention relates to the technical field of simulation, in particular to an SCE-MI protocol bridge and a simulation system. Background technique [0002] With the increasing scale and complexity of IC (Integrated Circuit, integrated circuit) design, traditional simulation tools make the simulation debugging time account for 70% of the total time of the entire IC design process, seriously affecting the efficiency of IC design. With the introduction of the software-hardware co-simulation method, people began to design a software-hardware co-simulation platform for simulation, which greatly shortened the IC design cycle. [0003] There are many methods and standards for the software-hardware co-simulation method, the most famous of which is the SCE-MI (Standard Co-Emulation Modeling Interface, Standard Co-Emulation Modeling Interface) protocol. With SCE-MI2.0, the simulation speed is greatly optimized by adding the flow interface Pipe (pipeline) in t...
