Embodiment Construction

[0050] Attached below Figure 1-6 The technical solutions of the present invention are further described through specific implementation methods.

[0051] Such as figure 1 As shown, the trigger signal synchronization system between multi-service boards in a kind of ATE semiconductor test equipment provided in this embodiment includes:

[0052] Backplane 1 and several service boards 2; service boards 2 are used to realize preset functions.

[0053] The backplane 1 is provided with a programmable logic device 3, and the programmable logic device 3 communicates with the service board 2 for receiving, processing, and distributing trigger signals with the service board 2. Through such settings, the service board 2 will trigger The signal is transmitted to the programmable logic device 3 , and the programmable logic device 3 receives, processes and distributes the trigger signal transmitted by the service board 2 .

[0054]In the programmable logic device 3 , the direction and t...

Abstract

The invention discloses a trigger signal synchronization system among multi-service boards in ATE semiconductor testing equipment, which belongs to the field of integrated circuit testing in the microelectronics industry. By setting the programmable logic device on the backplane, the interconnection synchronous trigger signal wiring of all service boards connected to the backplane is realized on the programmable logic device, which solves the problem of complex wiring on the backplane and solves the problem of various business The precise synchronization problem of sending the trigger signal of the board to other service boards, and it is easier to process the trigger signal synchronously.

Description

technical field [0001] The invention relates to the field of integrated circuit testing in the microelectronics industry, in particular to a trigger signal synchronization system between multi-service boards in ATE semiconductor testing equipment. Background technique [0002] The backplane is a type of PCB (Printed Circuit Board). Specifically, a backplane is a motherboard that hosts daughterboards or line cards for custom functions. The main function of the backplane is to "carry" the board and distribute functions such as power, signals, etc. to each daughter board for proper electrical connection and signal transmission. The service board and the backplane work together, and the communication connection between the service board and the backplane, and the backplane can guide the logical operation of the entire system. [0003] The current backplane wiring design has the following difficulties, combined with Figure 4 , taking 16 service boards as an example, the 16 ser...
