配置（configuration）是把用户的设计数据（位流）写入FPGA的内部存储器中的过程。配置数据可以由芯片主动从外部Flash获取，也可通过外部处理器/控制器将配置数据下载到芯片中。Logos系列FPGA使用SRAM单元存储配置数据，掉电后配置数据丢失，所以每次上电需要重新对FPGA进行配置。Logos系列FPGA支持如下六种配置模
• Moved “Board Layout for Configuration Clock (CCLK)” to after “Byte Peripheral Interface Parallel Flash Mode.” • Replaced Clock Management Technology (CMT) with Digital Clock Managers (DCM) throughout user guide. Chapter 7: • Revised the paragraph above Table 7-9. ...
Spartan-6 FPGA Configuration User Guide Spartan®-6 FPGAs are configured by loading application-specific configuration data—a bitstream—into internal memory. Spartan-6 FPGAs can load themselves from an external nonvolatile memory device or they can be configured by an external smart source, such...
在使用JTAG或者其他芯片来Program FPGA和FLASH时,我们最常用到的三个文件是bitstream文件、bin文件和mcs文件,最常遇到的问题是这三个文件有什么区别,在这一章节中我们不展开对文件内部详细数据格式的解析,主要针对这三个文件的主要差别和使用场景进行对比和描述。 在configuration userguide中,有如下描述: bit、bin和mcs...
Xilinx的FPGA,一般要求DONE管脚上外加一个上拉电阻(330欧, 4.7K欧等,不同系列要求不同,请参照对应的Configuration User Guide)。如果这个上拉电阻没有加,或者加的阻值过大或过小,那么DONE管脚无法在规定的时间里面达到高电平,此时内部配置控制器会认为配置失败了,典型情况就是DONE internal为高(内部数据接收完毕,内部...
