Abstract

The invention discloses a test system applicable to an NGFF (Next Generation Form Factor) slot in an extended circuit board, which is characterized in that a host board is simulated through a simulated circuit board, an extended circuit board with extended board NGFF slots is inserted into the simulated circuit board, then test circuit boards are respectively inserted into the extended board NGFFslots of the extended circuit board, and various corresponding tests are conducted on the NGFF slots by a fast peripheral component interconnection standard switching module and a test module, therebybeing capable of achieving the technical effects of providing low-cost NGFF interface testing and improving the test coverage.

Description

technical field [0001] The invention relates to a test system, in particular to a test system suitable for expanding NGFF slots in circuit boards, which performs various corresponding tests on NGFF slots by interconnecting standard switching modules and test modules with fast peripheral components. Background technique [0002] The NGFF interface is developed to replace the serial SCSI (Serial Attached SCSI, SAS) interface. The feature of the NGFF interface is that it adopts the Peripheral Component Interconnect Express (PCI-E) interface, so as to provide and have a fast peripheral. A solid state drive (SSD) with a standard interface for component interconnection is directly connected. [0003] However, for the test process of the NGFF interface on the expansion circuit board, in addition to testing through an external solid-state hard disk, it is also necessary to plug the expansion circuit board into the main board and use a solid-state hard disk to treat the NGFF interfac...
