On-chip bus test system based on Tbus bus standard

Abstract

The invention relates to an on-chip bus test system based on the Tbus bus standard. The system includes a main control unit and a slave terminal device end which are communicated with each other through data flow; a device internetwork is arranged between the main control unit and the slave terminal device end; a signal group set of the main control unit includes a data output signal group Out, a data injection signal group Inject, a parameter control signal group Param, a state signal group Status and a control signal group Control; a signal group set of the slave terminal device end includes a data output signal group Out, a data injection signal group Inject, a parameter control signal group Param, a state signal group Status and a control signal group Control. All test peripheral units are connected with a test bus in a hung mode to form the test system, a unified and rapid operation method is used for operating each test peripheral unit, the integration of the test system is accelerated, test defects are reduced, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computer communication applications, in particular to an on-chip bus test system based on the Tbus bus standard. Background technique [0002] The on-chip bus, as the name implies, is the bus on the chip. Many buses can be considered as on-chip buses, such as the address bus and data bus in the single-chip microcomputer chip, and the custom bus inside the programmable logic chip, all of which can be called on-chip buses. On-chip buses are generally easier to implement parallel multi-bit transfers than off-chip buses. [0003] Nowadays, the on-chip bus is widely used in various processor chips, such as the AMBA bus specification adopted by the well-known ARM core chip, which is used to connect the processor core and various peripherals. The AMBA standard 2.0 specification defines three sets of bus protocols: AHB (High Performance Bus), ASB (System Bus) and APB (Peripheral Bus). Each bus interface plays a...
