因此,assign语句满足上面的要去,因为无论何时右侧的任何输入发生变化,输出o都会更新。 // the module takes four inputs and performs a boolean// operation and assigns output to o.// the combinational logic is realized using assign statementmodulecombo(inputa,b,c,d,outputo);assigno=~((a&b)|c^...

隐形连续赋值在Verilog中是被允许的。 组合逻辑设计 assign语句常用于组合逻辑设计,如下的电路图: 使用Verilog描述为: // This module takes four inputs and performs a boolean // operation and assigns output to o. The combinational // logic is realized using assign statement. module combo ( input a,...
下面是用system verilog中的unique关键字修饰case综合 unique关键字的case 并行assign代码、结果如下 assignout=((sel==3'b001)&in[0])|((sel==3'b010)&in[1])|((sel==3'b011)&in[2])|((sel==3'b100)&in[3])|((sel==3'b101)&in[4])|((sel!=3'b001)&(sel!=3'b010)&(sel!=3'b011)...

The assign statement is used to assign a value to a variable. 2. always语句用于描述一个始终执行的逻辑块。 The always statement is used to describe a logic block that always executes. 3.在Verilog中,assign语句用于组合逻辑。 In Verilog, the assign statement is used for combinatorial logic. 4....
I defined an assign and case statement in my code as following: // NOT into a process assign cf_data = cf_we_n ? cf_data_in : cf_data_out; ... // State into a case statement, into a process. CM_WR_DATA: begin cf_we_n = 1'b0; i_wr = i_wr + 1; ...

Avoiding Assign Statements in Verilog NetlistsThe assign statement in Verilog allows two nets or ports to be connected to each other. In a netlist this occurs in one of two cases:An input port entering a module is directly connected to an output port without any logic in between:assign Monit...
