  • Xilinx FPGA集成电路的动态老化试验

      3 FPGA设计流程   完整的FPGA 设计流程包括逻辑电路设计输入、功能仿真、综合及时序分析、实现、加载配置、调试。FPGA 配置就是将特定的应用程序设计按FPGA设计流程转化为数据位流加载到FPGA 的内部存储器中,实现特定逻辑功能的过程。由于FPGA 电路的内部存储器都是基于RAM 工艺的,所以当FPGA电路电源掉电后,内部存储器中已加载的位流数据将随之丢失。所以,通常将设计完成的FPGA 位流数据存于外部存储器中,每次上电自动进行FPGA电路配置加载。   4 FPGA配置原理    以Xilinx公司的Qpro Virtex Hi-Rel系列XQV100电路为例,FPGA的配置模式有四种方案可选择:MasterSerial Mode,Slave Serial Mode,Master selectMAPMode,Slave selectMAP Mode。配置是通过芯片上的一组专/ 复用引脚信号完成的,主要配置功能信号如下:   (1)M0、M1、M2:下载配置模式选择;   (2)CLK:配置时钟信号;   (3)DONE:显示配置状态、控制器件启动;

  • XAPP144 -设计CPLD多电压系统

    Today’s digital systems combine a myriad of chips with different voltage configurations.Designers must interface 2.5V processors with 3.3V memories—both RAM and ROM—as wellas 5V buses and multiple peripheral chips. Each chip has specific power supply needs. CPLDsare ideal for handling the multi-voltage interfacing, but do require forethought to ensure correctoperation.

  • XAPP713 -Virtex-4 RocketIO误码率测试器

      The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in the Virtex-4 FPGA. Each MGT has its own pattern checker, but bothMGTs in a channel share the same pattern generator. Each channel can load a differentpattern. The MGT serial rate depends on the reference clock frequency and the internal PMAdivider settings. The reference design can be scaled anywhere from one channel (two MGTs)to twelve channels (twenty-four MGTs).

  • This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel.

    This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain
