For instance, consider the following example, where an HDL code produces a simplistic digital circuit design. module HalfAdder ( input A, // First input bit input B, // Second input bit output Sum, // Sum output output Cout // Carry output ); assign Sum = A ^ B; // XOR operation...
This is due to the fact that timing analysis tools always have problems with latches; glitch at enable pin of latch is another problem). One simple way to eliminate the latch with always statement is to always drive 0 to the LHS variable in the beginning of always code as shown in the...
The basic structure of code we will follow for creating a testbench to test the design is as follows:module design_name_tb (); //internal registers and wires reg <reg_names>; // All design inputs should be registers wire <wire_names>; // All design outputs can be wires //initialize...
It could cause problem in debug (for example: locating the port which is causing a compile error), when any port is added or deleted. 1 //--- 2 // This is simple adder Program 3 // Design Name : adder_implicit 4 // File Name : adder_implicit.v 5 // Function : This program...
