A method and device for realizing communication between a test platform and a user's design to be tested

Abstract

The present invention provides a method and device for realizing the communication between the test platform and the user's design to be tested. The method includes: generating a switch according to the top-level module in the DUT, and generating a parameter file according to the attribute information of the hardware input and output ports in the DUT, and sending the switch attribute information and parameter files of the device; parse the parameter file to obtain the name information of the hardware input and output ports and the name information of the corresponding switch and send them; according to the name information of the hardware input and output ports and the name information of the corresponding switch and The attribute information of the switch generates and sends a standard co-simulation modeling interface proxy; the test stimulus data is sent to the switch through the proxy, and the data response information generated by the switch is received through the proxy and sent to the test platform. The invention can increase the operability, flexibility and portability of the test platform, and the level of the communication interaction process is clear, which greatly facilitates the maintenance of programs by program designers.

Description

Technical field [0001] The technical field of design simulation of the present invention particularly relates to a method for realizing communication between a test platform and a user's design to be tested and a device for realizing communication between the test platform and the user's design to be tested. Background technique [0002] In the design of digital integrated circuits, after the design engineer uses HDL (Hardware Description Language, hardware description language) to complete the design, the HDL simulator needs to be simulated to verify whether the design meets the expected function. [0003] In the prior art, the design engineer sends the user design to be tested (DUT, Device Under Test) in FPGA (Fiels-Programmable Gate Array) through the test bench (Test Bench) running on the HDL simulator Test stimulus, the user will respond to the design to be tested and output information to complete the simulation. [0004] However, with the continuous increase of system design ...
