a:if(aflag)
begin
opt1 <= a;
opt2 <= b;
end
esle
begin
opt1 <= c;
opt2 <= d;
end
always@(posedge clk)
out_data <= opt1 +opt2;
b: if(aflag)
out_data <= a+b;
else
opt2 <= d;
end
always@(posedge clk)
out_data <= opt1 +opt2;
b: if(aflag)
out_data <= a+b;
else
out_data <= c+d;
4.用图表说明下列脚本命令
a: set_multicycle_path 4 -setup -from dffa/cp -to dffb/d
b: set_multicycle_path 4 -setup -from dffa/cp -to dffb/d
set_multicycle_path 4 -hold -from dffa/cp -to dffb/d
//这三个命令不一定完全正确,凭记忆大概是这个样子的
5. 5分频,用Verilog HDL/VHDL实现
6. `timescale 1ns/1ps 与`timescale 1ns/50ps分别代表的意义以及区别
7.分别用shell以及perl(或任一你熟知的脚本语言)将当前目录下所有".c"文件后缀改成".cc"
