Free running clock是指,上电以后无条件运行的时钟,比如晶振,上电以后就开始起震,不需要额外的附加条件限制,vivado锁相环pll输出的时钟,这个时候除了要满足上电以外,还需要pll没有被复位,而且输入时钟倍频后的vco在一定范围内,等诸多限制条件的满足,clk才能正常输出,所以PLL输出时钟就不是Free running clock,但经过...

到这一篇应该就是分析例子程序了,最重要地还是通过仿真来认识Aurora通信。 Aurora IP核的定制,基本都是默认的,为了简单起见,GT Selection中选择了一个通道(lane)。 文章末尾会分享工程文件! 例子工程预览 由于本IP核定制选择了: 因此,程序加入了一些debug的IP核例化。

The Flash*Freeze technology used in IGLOO and ProASIC3L devices enables entering and exiting Low Power mode, which consumes as little as 2 µW of power while retaining all SRAM and register data. Flash*Freeze technology simplifies power management through input/output (I/O ) and clock manage...
Clock 25MHz 外部时钟 使用DDR SODIMM接口引出了 106个GPIO(就是树莓派 CM3的金手指接口),可以自行设计底板使用,QQ群内也有群主设计的底板原理图和PCB,可以自行打样。 运行linux基于vexriscv,使用了litex框架(一个法国的团队基于nmigen实现的),具体可以参考github,有更详细的介绍。
