外部用的是有源晶振,20M,产生错误:Error: Input pin "CLK" feeds inclk ports of PLL "altpll0:inst2|altpll:altpll_component|pll" and other PLLs -- the input pin cannot feed inclk ports of more than 1 PLL
Error: Input pin "CLK" feeds inclk ports of PLL "altpll1:inst1|altpll:altpll_component|pll" and other PLLs -- the input pin cannot feed inclk ports of more than 1 PLL
