Universal computer simulation testing platform based on CPCI bus

Abstract

The invention discloses a universal computer simulation testing platform based on a CPCI bus. According to the universal computer simulation testing platform based on the CPCI bus, time is unified, expansion is convenient, and the universality is high. The universal computer simulation testing platform based on the CPCI bus comprises a CPCI bus chassis, expansion boards, a CPU module and a PKIO module, wherein the CPU module and the PKIO module are arranged in the CPCI bus chassis and connected with the CPCI bus. A secondary bus which meets the H.110 standard is formed on the CPCI bus chassis by means of expansion through an arranged J4 slot. Each extension board is connected with the CPCI bus and the secondary bus. The CPU module controls the expansion boards and the PKIO module through the CPCI bus. The PKIO module is connected with the secondary bus and is used for providing unified time mark signals for the expansion boards through the secondary bus. The time mark signals are generated through the PKIO module, synchronous clock signals are transmitted through the secondary bus, shunting transmission of control instructions and time signals is established, synchronous control over the expansion boards is achieved, and real-time simulation of a tested object is completed.

Description

technical field [0001] The invention relates to a computer test platform, in particular to a general-purpose computer simulation test platform based on CPCI bus. Background technique [0002] The traditional computer test platform only provides a single state test, which is difficult to meet the test coverage requirements of computer products. At the same time, the traditional computer test platform is too targeted. Different computer hardware product tests need to develop different test platforms, and software needs to be redeveloped, which makes repeated resource investment too large. Simulation platforms based on technologies such as PXI are limited by factors such as size, cost, and configuration capabilities, and have limited application fields and versatility, which cannot meet the current needs of computer test platforms; The simulation technology of multi-processor parallel computing cannot be unified in time, and there is a delay in the execution of control operati...

[0002] The traditional computer test platform only provides a single state test, which is difficult to meet the test coverage requirements of computer products

At the same time, the traditional computer test platform is too targeted. Different computer hardware product tests need to develop different test platforms, and the software needs to be redeveloped, which makes repetitive resource investment too large.

Simulation platforms based on technologies such as PXI are limited by factors such as size, cost, and configuration capabilities, and have limited application fields and versatility, which cannot meet the current needs of computer test platforms; The simulation technology of multi-processor parallel computing cannot be unified in time, and there is a delay in the execution of control operations, so it is difficult to achieve real-time simulation testing; not only the cost is high, but also the expansion space is small, and the configuration flexibility Poor, limited scope
