As a follow on from last week, one of the techniques I like to use to stimulate or capture data in our FPGA designs is a Linear Feedback Shift Register (LFSR).In the ten-plus years of this blog, I have never talked much about LFSRs, so I am going to focus this blog on exploring them as they are helpful for our FPGA designs. These days, we are a little spoiled with the modern fabric being so capable.LFSRs can be used for a range of applications in our FPGAs:Generating random test patterns – Lever...
