Build an AND gate using both an assign statement and a combinational always block. (Since assign statements and combinational always blocks function identically, there is no way to enforce that you're using both methods. But you're here for practice, right?...) 使用assign语句和组合always块构建...

creates an AND gate with two inputs and one output. You can simulate the code with same stimulus that we did in the previous example, which is reproduced here. initial begin // Initialize Inputs x = 0; y = 0; // Wait 100 ns for global reset to finish #100; #50 x = 1; #60...
If you're stuck, confused, or just want to share your AND gate epiphanies: Open an issue (it's like raising your hand, but with more markdown) Check out the comments in the code (we left breadcrumbs) Remember, in cosimulation as in life, sometimes you just need to AND it all toget...
