位操作符与逻辑操作符(Bitwise vs. Logical Operators) 前面,我们提到了各种布尔操作符有位操作符和逻辑(bitwise and logical )操作符(例如,normgate ),当使用向量时,这两种操作符类型之间的区别变得很重要。两个(N-bit)向量之间的按位运算对向量的每个位重复运算并产生(N-bit)输出,而逻辑运算将整个向量视为布尔...
Bitwise vs. Logical Operators a和b是输入,out_or_bitwise和out_or_logic分别是按位或与逻辑或的结果。 out_not是a和b的按位取反,b在高位。 写出代码如下: module top_module( input [2:0] a, input [2:0] b, output [2:0] out_or_bitwise, output out_or_logical, output [5:0] out_not )...

解答与分析 module top_module( input [2:0] a, input [2:0] b, output [2:0] out_or_bitwise, output out_or_logical, output [5:0] out_not ); assign out_or_bitwise = a | b; assign out_or_logical = a || b; assign out_not[2:0] = ~a; // Part-select on left side is ...
bitwise是按位运算,n输入就是n输出 logical是逻辑运算,n输入1输出 bitwise用来进行位运算,logical用来进行逻辑判断 防踩坑指南 module 一对module-endmodule中不能再嵌套module-endmodule。module的使用方法叫实例化,而不是调用 两种端口连接方法: // 已知有如下module声明modulemod (inputa,inputb,outputout );// 方...
Reduction operators are unary. They perform a bit-wise operation on a single operand to produce a single bit result. Reduction unary NAND and NOR operators operate as AND and OR respectively, but with their outputs negated. Unknown bits are treated as described before. Example 1 module reduct...

Problem 13 : Bitwise operators 本题将关注逐位逻辑运算符(&)和逻辑运算符(&&)之间的差别 逐位逻辑运算符:对于 N 比特输入向量之间的逻辑比较,会在 N 比特上逐位进行,并产生一个 N 比特长的运算结果。 逻辑运算符:任何类型的输入都会被视作布尔值,零->假,非零->真,将布尔值进行逻辑比较后,输出一个 1...
Bitwise Each bit is operated, result is the size of the largest operand and the smaller operand is left extended with zeroes to the size of the bigger operand. If a=3'b101, b=3'b110 and c=3'b01X Reduction These operators reduces the vectors to only one bit. If there are the charact...
