Xilinx FPGA learning notes 1-chipscope cannot observe the signal BUFG, xilinx-chipscope

Xilinx FPGA learning notes 1-chipscope cannot observe the signal BUFG, xilinx-chipscope Today, I started to try to use chipscope and wrote a simple routine of the Water lamp. There was no problem when I started the Integrated Wiring. However, after chipscope was added, an error was always reported. First case: Using chipscope cannot directly observe the global clock signal, that is, the BUFG signal ----- X

How to add Xilinx/Altera library in Modelsim

Currently, many people install Xilinx and Modelsim separately. Therefore, when using simulation libraries of chip manufacturers such as Xilinx or Altera, libraries cannot be found; because Modelsim does not own the simulation libraries of FPGA manufacturers, you must manually compile these libraries. Below I will introduce three methods to increase the library problem of

Reproduced the basic logic unit comparison of Xilinx and Altera FPGAs

Tribute to the originalHttp://blog.sina.com.cn/s/blog_6276db0e0101ary8.htmlTo compare Xilinx and Altera FPGAs, it is necessary to understand the structure of two giant FPGA, because of their respective interests, the two FPGA structure is different, the parameters are different, but can be unified to the LUT (look-up-table) lookup table.Take the example of Altera's Cyclone II series Ep2c35, as well as the xc3s500e of the

Xilinx-based Synthesize

Xilinx FPGA architecture

What is an FPGA? FPGA is a field programmable logic array, composed of programmable logic resources (LUT and REG), programmable wiring, and programmable I/O. The basic structure of Xilinx FPGA is the same, but with the development of semiconductor technology, FPGA's logic capacity is more and more rich, faster, embedded more and more hard core, such as: ARM processor, PCIE, Ethernet and so on. In the process technology, Xilinx's 7 Series FPGA uses the

Modelsim another way to compile Xilinx device libraries (save time)

I used to compile the device library with Modelsim for Xilinx, and it was very convenient and simple to compile the device library directly in the ISE, which was a bit of a long time. Since the last time, in their own computer installed mathtype,360 antivirus software will it as a Trojan. I thought it was 360 false positives, and the 360 security guards were shut down directly. Later, the software on the computer one after another, the problem is that
