Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a data communication method between an industrial computer system and a simulation test system and a semiconductor device simulation system. Background technique [0002] When using the simulation test system (which can generally be realized based on simulation test software) to perform functional tests on the control system software of the machine under test, the simulation test system is required to simulate various hardware devices and the control system under test (that is, the industrial computer control system, It is generally set in the lower computer) for data interaction. At this time, the simulation test system not only needs to simulate and generate the status signal of the hardware device to send to the industrial computer control system, but also needs to accurately receive and analyze the control instructions from the industrial computer control system.

Problems solved by technology

[0005] Due to the different software test items, the hardware devices that need to interact with the industrial computer control system are also different, and the communication methods of these hardware devices are also different. It is difficult to unify the data type and length, which makes the simulation test system not suitable for all hardware. The communication method of the equipment, and for the communication method that cannot be applied, it is necessary to build a special environment according to the communication method, which not only increases the cost of manpower and material resources, but also deviates from the original purpose of software testing
