措施:缩短工程路径。 11. [Synth 8-7023] instance 'u_count' of module 'count' has 7 connections declared, but only 6 given。 原因:信号位宽多余。 措施:给与信号正确的位宽,或不管也可以,Vivado 会自动优化多余的位线。 12. ordered port connections cannot be mixed with named port connections。 原...

一个组件用常见的模块(module)来表示,组件之间的连接由实例化(instantiation)声明实现,实例化声明规定一个组件在另外一个组件或电路中的实例,赋予标识符,并用关系列表设定信号与端口之间的联系; 除了自己设计的组件外,结构化Verilog还支持实例化预定义的原语:逻辑门、寄存器、Xilinx特定的原语(如CLKDLL、BUFG),这些原语...
7. [Synth 8-1031] cnt is not declared。 原因:信号没有被声明,多出现在中间信号。 措施:给中间信号添加声明,如 reg、wire。 8. The debug port 'u_ila_0/probe4’ has 1 unconnected channels (bits). This will cause errors during implementation。
