    Adder Circuit
AI Thread Summary
To create a testbench for a 1-bit adder circuit with inputs A, B, and Cin, it's important to structure it with multiple rows representing clock cycles and columns for input values and outputs. Using loops for each input can help automate the testing process. The choice of tool for running the testbench can influence the syntax and structure, so checking the documentation for examples is recommended. Each row in the testbench acts as a state, with clock transitions moving through these states. Properly designing the testbench ensures thorough testing of the adder's functionality.

So, I am trying to design a testbench for 1-bit adder first, I have 3 inputs A, B and Cin with 2 outputs Sum and Cout;
would I just have 3 loops, one for each input?
thanks.

What tool are you using for running your testbench? Does the documentation give some examples of testbenches? Usually a testbench will consist of a number of rows, corresponding to clock cycles. The columns in each row correspond to the input values and previous output values. The rows are like "states", and the clocking that transitions you from row to row sequences the states. The syntax can vary some, depending on the tool that you use to run the testbench.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
