Hello everyone, today we are going to discuss a common topic in the FPGA community – the “three-year foundation.” Yes, that infamous “three-year rule” that terrifies countless beginners and makes experts smile. Some say it’s a superstition, while others claim it’s a truth. So, the question arises: is this concept reliable? Today, we will delve … Read more
Follow usLearn Embedded Together and grow together The core of a timing diagram is the relationship between time and the level changes. Time progresses from left to right, and levels are represented as high or low, typically denoted by 0 and 1. A timing diagram helps us understand the changes of various signals in a … Read more
The execution modes of FPGA are download mode and programming mode. 1. FPGA is a type of digital integrated circuit chip, known as “Field Programmable Gate Array”. An important feature of FPGA is its programmability, which allows users to specify a particular digital circuit through programming. The components of FPGA include CLB (Configurable Logic Block), … Read more
Don’t let these misconceptions hinder your growth curve At two in the morning, the lights in the lab are still on. You stare at the flashing timing error messages on the screen, having modified the Verilog code for the 17th time, yet the development board remains silent as a stone. The coffee beside you has … Read more
When a microcontroller or FPGA sends SPI control signals to a phase-locked loop (PLL) chip, it often requires a series connection of a 22 ohm or 33 ohm resistor. What is the reasoning behind this? Impedance discontinuities can cause electromagnetic wave reflections, which in turn can lead to signal distortion. Therefore, impedance matching is often … Read more
