ug835-vivado-tcl-commands
说明: Vivado是Xilinx最新的FPGA设计工具,支持7系列以后的FPGA及Zynq 7000的开发。与之前的ISE设计套件相比,Vivado可以说是全新设计的。无论从界面、设置、算法,还是从对使用者思路的要求,都是全新的。看在Vivado上,Tcl已经成为唯一支持的脚本,此文件是vivado是tcl命令的集合。(Vivado is Xilinx's latest FPGA design tool that supports development of FPGAs and Zynq 7000s in the 7 series and beyond. Compared with the previous ISE design suite, Vivado can be said that the new design. No matter from the interface, settings, algorithms, or from the user ideas, are new. Look at Vivado, Tcl has become the only supported script, this file is vivado tcl command collection.)

四位全加器的Verilog源代码
应用背景小的verilog程序,实现一四位全加器的功能。它有两大模块。一个是四位全加器,另一个是一位全加器,它是采用组合逻辑,不复杂,但简洁明了。这将是一个很好的第一步,学习verillog。适合初学者练习。关键技术只是Verilog和组合逻辑实现一四位加法器。它建立了2个模块。一个是大 ;框架,其他作品如子功能。家庭 ;spratan-3e XC3S100E,设备,包装cp132。全加器意味着它有一个进位,它可以显示的进行,如果过流发生。

spi
VHDL实现SPI功能源代码
-- The SPI bus is a 3 wire bus that in effect links a serial shift
-- register between the "master" and the "slave". Typically both the
-- master and slave have an 8 bit shift register so the combined
-- register is 16 bits. When an SPI transfer takes place, the master and
-- slave shift their shift registers 8 bits and thus exchange their 8
-- bit register values.(SPI realize the functional VHDL source code The SPI bus is a 3 wire bus that in effect links a serial shift register between the )
