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
Welcome FPGA engineers to join the official WeChat technical group. Fanout refers to the number of lower-level modules directly called by a module. If this value is too large, it directly manifests as a large net delay in FPGA, which is not conducive to timing convergence. Therefore, when writing code, one should try to avoid … 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
