1 Introduction DDR2 (double data rate2) SDRAM is a new generation memory technical standard developed by JEDEC (Joint Committee for electronic equipment engineering). It is the biggest difference from the previous generation of DDR memory technical standards: although the basic method of transmitting data at the same time with the clock rising/falling edge, DDR2 has twice the DDR pre-read capability (that is, 4-bit pre-Access Technology ). In addition, DDR2 also adds the ODT (with built-in cor

ArticleDirectory Fault 1 Summary Introduction Whether it is customer feedback or your own experience, USB-blaster cannot download and configure FPGA from time to time. The reasons are as follows: 1. The JTAG-related pins on FPGA Devices are faulty; 2. the USB-blaster is broken; 3. The 10-pin JTAG cable is not properly pressed. Among them, Article 1 has brought the most serious damag

Abstract: The state machine frequently used in FPGA/CPLD design often has some stability problems. Some solutions are proposed in this paper. Experiments show that this method effectively improves the overall efficiency. With the emergence and development of large-scale and ultra-large FPGA/CPLD devices, the application of EDA technology, which uses HDL (hardware description language) as a tool and
