在VHDL中,生成语句(Generate Statement)用于在设计中生成重复的结构,if语句是生成语句中的一种条件语句。 在生成语句中的if语句中,可以根据条件来控制生成的结构是否被实例化。if语句的语法如下: 代码语言:txt 复制 if condition generate -- 生成的结构 else -- 其他情况下的结构 end generate; 在if语句中,condit...

表达式n-1 when 条件n-1 else 表达式n; VHDL 语言程序执行到该语句时,首先要进行条件判断,之后才进行信号赋值。如果满足条件,就将该条件前面那个表达式的值赋给目标信号;如果不满足条件按,就继续 判断,直到最后一个表达式,如果前面的条件均不满足就无条件的赋值给最后一个表达式,因为最后一个表达式赋值无需条件。

if expression statements elseif expression statements else statements end Description if expression, statements, end evaluates an expression, and executes a group of statements when the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or...
The If block, along with If Action Subsystem blocks that contain an Action Port block, implements if-else logic to control subsystem execution.
