When CPLD sees it is pulled low, it keeps pulling it low till the operation is finished
clk_out:continues here.... after the operation is finished, start_cmd <= 'Z' is "executed" 我有start_cmd信号连接到我的CPLD当另一个器件想要CPLD开始某些操作时,它会将start_cmd拉到低电平。当CP

在嵌入式编程中,当描述硬件时,通常需要在HW工程师设计时将结构元素放置在已知的预定义位置。packed__)) sFPGA { ushort DiscreteInput;//CPLD_Versionis required to be at offset 0xA0, so 0xA0-0x24-2=0x7A};
现在,我对人工计算和结构改变时可能出现的错误感
