1.Warning-[UII-L] Interfaec not instantiated
Interface ‘xxx_interfeace’ defined in logic library ‘work’ is never instantiated design.It will be ingored
工程中某些定义的interface没有被实例化,验证平台搭建中比较常见,可忽略。
2.Warning-[PCWM-W] Port connection width mismatch
……
The following 32-bit expression is connection to 1-bit port
有时候此类warning出现在对module例化过程中,比如直接对某一个1-bit的端口直接tie 0便会报此warning,改写为1’b0便可以消除此warning
3.UVM_WARNING @1.00ns reporter [CMPNFD] Component matching
‘xx.xx.amba_env_die0’ was not found in the list of uvm_components
Error-[NOA] Null object access
特别常见的一种空对象错误,报错的本质体现在WARNING中,引用路径中为发现amba_env_die0没有例化,但是自己确实在sub_env中例化了amba_env啊,为什么有问题?仔细一下&#x
