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,...

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。
Avoid adding a space after else within the elseif keyword (else if). The space creates a nested if statement that requires its own end keyword. Extended Capabilities C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. HDL Code Generation Generate VHDL, Verilog and System...

Generate statements are used to create different static implementations. What you are really after is using en_logic as a multiplexer control. in(1 to 4) <= rx_inp(1 to 4) when (en_logic = '0') else rx_inp(5 to 8); Cheers, Dave Translate 0 Kudos Copy...
