It is also possible for us to use an else-if type statement here but the else statement is more succinct. The behaviour is the same in both cases as the signal can only ever be 0b or 1b in a real circuit. SystemVerilog Case Statement We use the SystemVerilog case statement to select...

The if statetement in verilog is very similar to the if statements in other programming languages. We will now write a combinatorial verilog example that make use of if statement. Let us try to design a priority encoder. Our priority encoder has 4 bit inputs - call them x[4], x[3],...
what is the correct syntax for if statement with multiple conditions? I've written(which works): always@(posedge iGO or negedge iRST)//on key press event begin if(!iRST) go_en <= 0; else if (done == 1) go_en <= 0; else begin if(iGO) //if go key pressed enable ADC go_...
当条件不互斥的时候,case和if会综合出带优先级的电路,对于case来说,如果 condition1 为真,则执行 true_statement1 ; 如果 condition1 为假,condition2 为真,则执行 true_statement2;依次类推。如果各个 condition 都不为真,则执行 default_statement 语句。后续仿真会体现上述内容。

“Verilog 2001标准(IEEE 1364-2001)第132页: The case item expressions shall be evaluated and compared in the exact order in which they are given. 指出了case是串行有优先级。又: Apart from syntax, the case statement differs from the multiway if-else-if construct in two important ways: ...
在上面的Verilog代码中,我们定义了一个模块 if_statement_example,包括输入信号 clk、rst、data_valid 和 data_in,以及输出信号 data_out。在always块中,我们使用if语句对reg变量 count 和 flag 进行判定。 当接收到 rst 信号时,我们将 count 和 flag 的值重置为初始值。当 data_valid 信号为高电平时,我们将...
