Let’s start with the conclusion:If you are exceptionally talented, have a strong background, and possess great ambition, then without a doubt—design (DE) is your first choice. However, if you are an ordinary person looking to secure a position in a large company, earn a good salary, and live a decent life, then verification (DV) may … Read more
First, let’s clarify what is meant by “timing” here, which refers to the logical relationships of a set of signals, rather than timing parameters like steptime and holdtime. If you want to understand why this article exists, please refer to the series “Where is FPGA Going” and “What HLS Does FPGA Need”. Here, we focus … Read more
IC design, or Integrated Circuit Design, is a discipline of electronic engineering and computer engineering, mainly focusing on the design of integrated circuits (IC) using specialized logic and circuit design techniques. This article mainly introduces classic books on digital IC design. Let’s follow along to learn more. 1. ‘Advanced Digital Design with Verilog HDL’ This … Read more
How many steps are needed to put an elephant in the fridge? Three steps: open the fridge door, put in the elephant, and close the door. So how many steps are needed to create a chip? Also three: design the chip, manufacture the chip, and finally package and test the chip. However, is making a … Read more
Fixed-point decimal division is much more complex than addition and multiplication, but the basic idea of the algorithm is still quite simple. Similar to integer division, the core idea of the algorithm is to convert the division operation into shift and subtraction operations. From a practical implementation perspective, there are generally two methods: One is … Read more
Recently, our company has been preparing for the FPGA localization plan and conducting market research. We have also arranged discussions with market engineers from several domestic FPGA manufacturers.Regarding FPGA, I consider myself a latecomer. After graduating, I worked on MCU development for about a year, and later, due to project needs, I started to engage … Read more

In-Depth Hardware Preparation and Planning Before starting the project, hardware selection and planning are crucial. In addition to considering the type of PCIe interface on the development board, attention must also be paid to its logic resources, storage bandwidth, etc. Taking Xilinx’s KCU105 development board as an example, it not only has a high-speed PCIe … Read more
1. Constraint Files There are three types of constraint files in Xilinx ISE FPGA design: User Constraint File (.UCF), Netlist Constraint File (.NCF), and Physical Constraint File (.PCF). These can achieve timing constraints, pin constraints, and area constraints. Users write UCF files during the design input phase, then the UCF file generates the NCF file … Read more
