1. Env_config中：Invalid type 'uart_config'. Please check the type of the variable 'UART_cfg'

                    Invalid type 'spi_slave_config'. Please check the type of the variable 'SPI_slave_cfg'

                         (vlog-2730) Undefined variable: 'UART_cfg'.

                         (vlog-2730) Undefined variable: 'SPI_slave_cfg'.

可能是顶层没有Import或者include底层的代码

因为我们输入了import my\_pkg::* ;所以仿真器才认识e\_signal

我们将import my\_pkg::***删掉再仿真，**仿真器会报出编译错误

** Error: **.sv(23): Invalid type'e_signal'. Please check the type of the variable 'my_sig'.

** Error: **.sv(30): (vlog-2730) Undefinedvariable: 'GREEN'.
