function void fill_packet(input logic[63:0] data_in,output packet_t data_out); data_out.data = data_in endfunction 没有输出,通过输出变量data_out输出 4:在verilog里function只有input,没有output,返回值就是函数值;但在sv里,function增加了output,inout变量 5:参数方向类型缺省时,类型默认为logic,方...
1. SV中变量存储 Variables declaredoutsideamodule, program, interface, checker, task, or functionare local to the compilation unit andhave a static lifetime (exist for the whole simulation). Variables declaredinsidea module, interface, program, or checker, butoutsidea task, process, or function...
Function或task的生命期仅见于Verilog语言。Verilog早期仅有静态生命期(static lifetime),无论是function还是task,用来描述硬件,无论调用多少次,同一个Task或者function都是分配一个地址。 数字IC小站 2020/07/01 3.3K0 用SV写一个蒙哥马利模乘的参考模型
SystemVerilog可以给module或interface加上这个关键字,使得module或interface内的过程默认为automatic,而不需要给内部申明的每个function/task加automatic关键字。 例一我们可以试试给递归函数factorial加上automatic关键字,使函数具有自动属性。 ...functionautomaticintegerfactorial(input[31:0]operand);... 也可以给module加...
