Consider a 2:1 mux; what will the output F be if the Select (sel) is "X" ? What is the difference between blocking and nonblocking assignments ? What is the difference between wire and reg data type ? Write code for async reset D-Flip-Flop. Write code for 2:1 MUX using different...

Parentheses may be omitted if the code formatting conveys the same information, for example when describing a priority mux. 👍 assign foo = condition_a ? a : condition_b ? b : not_a_nor_b; Comments C++ style comments (// foo) are preferred. C style comments (/* bar */) can also...
高度的可综合性——MUX,综合出来的逻辑具有优先级,靠前的逻辑少、路径短 4.2 case条件语句 5.循环语句 forever: 无限循环,通常用于生成时钟: forever #10 clk = ~clk; repeat: 执行括号内表达式指定的循环次数,如果表达式对应为不定态或高阻态,则不执行 while: 括号内表达式为真则进入循环,否则退出循环 for...
You could download file mux_without_default.v here The example above shows how to specify multiple case items as a single case item. The Verilog case statement does an identity comparison (like the === operator); one can use the case statement to check for logic x and z values as show...
