Embodiment Construction

[0016] The invention is a network-based software and hardware co-simulation platform. Now, a specific implementation of the software-hardware co-simulation platform of the present invention will be described in conjunction with the accompanying drawings.

[0017] Fig. 1 shows the composition diagram of the system of the present invention. The system consists of three parts: PC terminal 101 , debugger 102 and target board 103 . The user completes the design of the DUT on the PC terminal 101 . Since the DUT module must rely on the support of the co-simulation interface module 108 to receive the excitation signal and return the response signal, the user DUT module 107 must synthesize, layout and route together with the co-simulation interface module 108 to generate the FPGA configuration file. The configuration file is downloaded to the target FPGA 106 of the target board 103 through the debugger 102 via the JTAG interface 110 . Both the excitation signal vectors in the Vector...

Abstract

The invention discloses a method for realizing software and hardware co-simulation platform based on network, belonging to the technical field of SOC simulation and verification, which comprises a PC terminal for running the software part, a target board for simulating the hardware part, and a debugger for connecting the PC terminal and the target board mutually. The invention has the advantages that the simulation support to Vector mode and Co-simulation mode can be realized on a unitive multi-mode simulation system; the occupation on I / O resources is reduced greatly due to the communication between the debugger and the target board adopting serial-parallel conversion method; and the software part is communicated with the hardware part via Ethernet to support remote co-simulation.

Description

technical field [0001] The invention belongs to the technical field of functional simulation of integrated circuit chips, in particular to software and hardware co-simulation and verification technology. Background technique [0002] System-on-chip (SOC) design has developed rapidly in recent years. The biggest difference between it and ASIC is that in addition to a large number of hardware modules, it also contains a large number of software, such as operating systems, drivers, communication protocols, and various applications. Its design complexity is much higher than that of traditional integrated circuit chips. Therefore, the simulation of the SOC chip becomes very difficult, [0003] It is not only necessary to simulate the hardware part of the system, but also to simulate the software part, that is, to carry out software and hardware co-simulation. [0004] Software-hardware co-simulation technology divides a complex SOC design according to IP modules, uses module-ba...
