Description: 本代码介绍了使用VHDL开发FPGA的一般流程，最终采用了一种基于FPGA的数字频率的实现方法。该设计采用硬件描述语言VHDL，在软件开发平台ISE上完成，可以在较高速时钟频率（100MHz）下正常工作。该设计的频率计能准确的测量频率在1Hz到100MHz之间的信号。使用ModelSim仿真软件对VHDL程序做了仿真，并完成了综合布局布线，最终下载到芯片Spartan-II上取得良好测试效果。-the code on the FPGA using VHDL development of the general process, finally adopted a FPGA-based digital frequency method. The design using VHDL hardware description language, the software development platform ISE completed, the higher speed clock frequency (100MHz) under normal work. The design of the frequency meter can be accurately measured in a frequency of 100MHz between Hz signal. Use ModelSim VHDL simulation software to do the simulation process, and completed a comprehensive layout cabling, downloaded to the final chip Spartan-II made good on the test results. Platform: |

Description: DDR SDRAM控制器的VHDL源代码，含详细设计文档。
The DDR, DCM, and SelectI/O™ features in the Virtex™ -II architecture make it the perfect
choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock
Manager (DCM) provides the required Delay Locked Loop (DLL), Digital Phase Shift (DPS),
and Digital Frequency Synthesis (DFS) functions. This application note describes a controller
design for a 16-bit DDR SDRAM. The application note and reference design are enhanced
versions of XAPP200 targeted to the Virtex-II series of FPGAs. At a clock rate of 133 MHz,
16-bit data changes at both clock edges. The reference design is fully synthesizable and
achieves 133 MHz performance with automatic place and route tools.-DDR SDRAM controller VHDL source code, including detailed design documents. The DDR, DCM, and SelectI/O Platform: |

Description: 序列检测器可用来检测一组或多组由二进制码组成的脉冲序列信号，这在数字通信领域有广泛的应用。当检测器连续收到一组串行二进制码后，若这组码与检测器中预制的码相同，输出为A，否则输出为B。序列检测I/O口的设计如下：设Din是串行数据输入端，clk是工作时钟，clr是复位信号，D是8位待检测预置数，QQ是检测结果输出端。-Sequence detector can be used to detect one or more sets consisting of binary code from the pulse sequence signal, which is a broad field of digital communication applications. When the detector continuously received after a group of serial binary code, if this group of pre-code and the code detector in the same output as A, otherwise the output B. Sequence detection I/O port design are as follows: Let Din is the serial data input, clk is work the clock, clr is a reset signal, D is the 8-bit preset number to be detected, QQ is the test results output.
