Abstract

The invention provides a detection device of field programmable gate array (FPAG) control equipment and a method thereof. The detection device comprises a memory network card unit and an FPGA. The memory network card unit comprises a memory and a physical layer (PHY). The FPGA comprises a memory controller, a measurement and control (MAC) controller, a memory detection module, an MAC detection module and a result summary module. The memory controller and the MAC controller respectively control the memory and the PHY. The memory detection module and the MAC detection module are respectively connected with the memory controller and the MAC controller. The result summary module is respectively connected with the memory detection module and the MAC detection module. According to the detection method, the memory is detected in the mode that address line going 1, address line going 0, data line going 1 and data line going 0, and memory area blocks of a memory are detected in a single burst mode. The detection device of FPAG control equipment and the method thereof are capable of effectively locating possible hardware faults and checking correctness of each control access.

Description

technical field [0001] The invention belongs to the technical field of signal detection, and in particular relates to a detection device and method of an FPGA control device. Background technique [0002] In the current network communication, the main chip of some devices is implemented by FPGA, which can integrate functional processing components such as MAC controller, DDR controller, and QDR controller. Correspondingly, there are generally MAC access, On-board components such as memory slots and QDR storage particles. After the PCB board is soldered, it is necessary to check the correctness of these internal and external functional parts to eliminate possible logic faults or hardware faults. [0003] After the existing FPGA board equipment is soldered, the electrical detection of the FPGA board equipment is generally to measure the resistance or voltage on the board to determine whether there is a hardware fault, but for some PCB boards, the inner layer or no The correc...

Problems solved by technology

[0003] After the existing FPGA board equipment is soldered, the electrical detection of the FPGA board equipment is generally to measure the resistance or voltage on the board to determine whether there is a hardware fault, but for some PCB boards, the inner layer or no The correctness of the signal line of the measurement hole cannot be measured; the internal functions of the FPGA also need to be programmed with a complete firmware program to debug the system. Even if a problem is found during the debugging process, it cannot be quickly located whether there is a hardware failure cause

[0004] Patent No. ZL200510080017.3, titled Invention of a Chip Interface Detection Device and Method, discloses a method of using external detection devices and internal detection devices to detect the correctness of external memory module control or data. The memory device has guiding significance, but this method has the defect that many devices are used and the detection content is single. It can only detect the storage module and cannot detect other control devices.
