Description

technical field [0001] The invention belongs to the technical field of testing, and in particular relates to an automatic configuration device and method for a multi-mode multifunctional testing instrument. Background technique [0002] Multi-mode multi-function test instrument is a kind of comprehensive test instrument. Most of the traditional design methods use ASICs to complete the processing of different measurement functions, that is, the processing functions it can complete are determined at the design stage, and its processing functions are determined after the design is completed. The functions are completely solidified. For example, once the design is completed, only the finalized functions of the design can be completed. For multi-mode and multi-function testing instruments, the software programs involved mainly include the host program, FPGA program, DSP program, and single-board programs for each measurement. The traditional method is generally more convenient fo...

Problems solved by technology

For multi-mode and multi-function testing instruments, the software programs involved mainly include the host program, FPGA program, DSP program, and single-board programs for each measurement. The traditional method is generally more convenient for configuring the programs run by the host. It is enough to control or overwrite the installed program on site, but for onboard programs such as FPGA programs, DSP programs and individual board programs, they are basically digital processing algorithm programs, which have fixed IP core information. In order to protect the algorithm, Basically, it is recorded into the readable memory of the integrated chip by burning, so it is very inconvenient to upgrade

[0003] The traditional method is through online programming, which needs to return the instrument to the manufacturer and upgrade the program through online programming through the JTAG interface. This method is inefficient and takes a long time.

[0004] Another way is to upgrade the main program remotely, but the FPGA program, DSP program and the programs of each board cannot be upgraded. This method can only automatically configure some programs, which has certain limitations and cannot meet the requirements. engineering application

[0005] Most traditional instruments and meters use ASICs to complete the processing of the digital part. It is very difficult to update the digital processing algorithm flow, that is, the processing functions that it can complete are determined in the design stage, and it is difficult to adapt to the ever-changing upgrade and update requirements.

The design of multi-mode and multi-functional test instruments is based on hardware, which lacks flexibility and poor reconfigurability. Once there is an upgrade demand, it is difficult to complete automatic upgrades
