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

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

The typical PLD is composed of "and", "non" array, with "and or" expression to implement any combination logic, so PLD can complete a large number of logical combinations in product and form.The 3rd stage Xilinx and Altera respectively introduced the standard gate array similar to the FPGA and similar to the PAL structure of the extended CPLD, improve the speed of the logic, with the architecture and Logic unit flexible, high int

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
The so-called synthesis means to translate design inputs such as the HDL language and schematic diagram into logical connections (I .e., network tables) between logical units registered with, or, non-users and RAM and triggers ).

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
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.

Later, the software on the computer one after another, the problem is that
