The syntax for the attribute statement is the same, except that the <identifier> names a primitive earlier in the compilation unit and the statement is placed in the global scope, instead of within a module. The semicolon is not part of a type attribute....
You can assign to a register (reg data type) the value of a net (wire), constant, another register, or a specific value. Example - Bad procedural assignment 1 module initial_bad(); 2 reg clk,reset; 3 wire enable,data; 4 5 initial begin 6 clk = 0; 7 reset = 0; 8 enable =...
This line is where the "magic" happens. Up to this point, your code has described all inputs and outputs, and now you will manipulate outputs based on those inputs. assign is another Verilog keyword; one you will use over and over again. Assign statements are permanent descriptions of an...
