编译通不过提示什么?
我想这么连接,但是编译出错了,求指教,错误是:
Error: Clock input port inclk[0] of PLL "pll1:inst12|altpll:altpll_component|pll" must be driven by a non-inverted input pin or another PLL, optionally through a Clock Control block
Info: Input port INCLK[0] of node "pll1:inst12|altpll:altpll_component|pll" is driven by clkopt:inst9|Mux0 which is COMBOUT output port of Combinational cell type node clkopt:inst9|Mux0
