VCO频率使用PLL支持页面上的公式计算: http : //www.altera.com/support/devices/pll_clock/basics/pll-basics.html 。由于舍入误差,Quartus®II可能会报告VCO频率与使用这些方程计算的略有不同。 VCO频率显示在Fitter – Resource Section – PLL Summary中的Quartus II编译报告文件中。对于那些关注PLL精度的人,可以确保输出频率与输入频率和计数器设置直接相关,并且由于舍入误差,Quartus II中的报告可能略微偏离。使用PLL摘要和PLL使用情况报告中显示的M,N和后缩放计数器值来计算PLL生成时钟的准确频率值。
