Abstract

A method for screening and detecting an FPGA configuration PROM, relating to a method for screening and detecting an FPGA configuring a PROM, solving the problem that the existing PROM screening and detection method is easy to reduce the signal integrity of the configuration process, the configuration process is easily disturbed, and at the same time, it is easy to increase the volume and not Suitable for problems such as application in compact loads, including screening and detection systems, screening and detection systems include PCs, controllers and n groups of PROM circuits set in high and low temperature boxes; each group of PROM circuits includes current detection circuits, PROMs can be Adjust the power supply and the driver with adjustable amplitude and level; the controller is respectively connected with the current detection circuit of each group of PROM circuits, the adjustable power supply of PROM, and the driver with adjustable amplitude and level; The method of screening and testing in advance, by changing the ambient temperature, power supply voltage, control signal level and readout clock frequency, while monitoring the working current of the device, the device with poor performance is eliminated in advance, and the risk of device drop soldering is reduced.

Description

technical field [0001] The invention relates to a method for screening and detecting FPGA-configured PROMs, in particular to a method for screening and detecting OTP-type PROMs based on FPGA-configured aerospace applications. Background technique [0002] In aerospace applications, in order to improve the adaptability of the space environment, OTP (one-timeprogrammable) type PROM is usually used to store the configuration data of FPGA devices. Even if the OTP type PROM can read back the data after burning, the read data (including the first three, the last three and the accumulated sum) is the same as the original data, and the configuration may also appear when it is soldered on the circuit board that has passed the layer-by-layer inspection. If it fails, it needs to be disassembled and re-soldered. In the process of multiple disassembly, there is a risk that the entire board will be scrapped; if the PROM is soldered on a small circuit board and connected to the FPGA throug...
