Title:
ELECTRONIC CONTROL DEVICE AND METHOD FOR DIAGNOSING VEHICLE-MOUNTED DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/145092
Kind Code:
A1
Abstract:
Provided is a highly reliable, FPGA-mounted electronic control device in which FPGA random test times can be shortened and an error location can be easily identified. The present invention is provided with a pseudo-random number generator and a seed-value modification timing generator, and is characterized in that the seed-value modification timing generator has a counter circuit for counting the number of test steps and a seed-value storage unit for storing count values of the counter circuit and seed values with which rewriting by the pseudo-random number generator is carried out.
