Abstract

The invention provides a debug card used for debugging the functions of a computer and spliced on the slot of a motherboard, which comprises a display device and a programmable logic device. The display device comprises a VGA connector which can be connected with a display, the programmable logic device comprises a data latching module used for latching the debugging datum of the computer, and a data conversion module used for converting the debugging datum of the computer, the data conversion module is connected with a VGA controller, and the VGA controller is connected with the VGA connector. Moreover, the invention also provides a computer debugging method.

Description

technical field [0001] The invention relates to a debugging card, in particular to a debugging card for effectively detecting a computer. The invention also relates to a computer debugging method. Background technique [0002] At present, computers are widely used, and some failures will occur in computers after long-term use. How to repair computers is a big problem now. [0003] There are many debugging cards used to detect the working state of the computer in the industry, among which there is a debugging card, which is plugged into the PCI (Peripheral Component Interconnection) slot of the motherboard, and it includes a display device, which is a plurality of light-emitting diodes Composition, the display device can display the digital symbols of the test process, such as data (Data), address (Address), command (Command) and bit group enable (BE#), etc. [0004] The debugging card latches the signal states of the PCI bus cycle to be inspected, such as addresses, data, ...
