Cyclone 10 gx器件

使用Cyclone 10 gx器件时,由于把硬件给的管脚tcl脚本拉到工程里面了,编译后发现一个Critical Warning如下

Critical Warning(18326): The design pin 'C10_CLKUSR~pad' has been assigned to CLKUSR pin location 'Y15'. Quartus Prime auto-reserves the CLKUSR pin for calibration of transceivers and certain IOs. If the pin 'C10_CLKUSR~pad' will not be assigned a 100-125MHz clock, you must remove the location assignment on it. Otherwise, to remove the critical warning use the QSF assignment 'set_global_assignment -name AUTO_RESERVE_CLKUSR_FOR_CALIBRATION OFF'.

因为此时钟端口是C10器件的专用时钟引脚,用来给高速收发器做校准用的,因此出现了报错;

解决方法:

1、顶层设计中删去该引脚的说明,但是sdc约束文件中可以对该端口进行约束;

2、约束文件中关闭自动保留功能,但确定不使用高速通信的时候;

暂时记录这么多,如果有错误,欢迎指正;
