PLLE2_ADV原语里面的内容其实和MMCME2_ADV的内容是大致相同的,有了MMCME2_ADV的基础,我们对于PLLE2_ADV原语就更容易理解了,下面的代码依然是生成IP核Clocking Wizard,输入为100MHz,输出为200MHz和50MHz时钟,提取RTL代码后获取到的PLLE2_ADV的实例化例子,大家可以自行去理解一下。 PLLE2_ADV#(.BANDWIDTH("OPTIMIZE...
MMCME2_ADV与PLLE2_ADV在本质上实现了与MMCM和PLL相同的功能,即通过输入时钟分频或倍频产生所需的不同频率输出时钟。我们常使用的锁相环(PLL)或频率发生器(Clocking Wizard)在FPGA设计中扮演着关键角色。通过打开FPGA的时钟IP核,我们可以直观地看到其内部封装了MMCM和PLL模块,这为理解原语的使用提...
