#Alu in verilog code

Kindly help.ДЄlso, no matter how I change the order of simulation, the first operation is always producing unknown('x') state in Y. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. I have attached the testbench sims below. But the answer produced is 16.ДЄnother is a case of 4-1 which should be 3, but the answer stored is 13. Incase of ALU, I observe that the the answer during subtractions always has a '1' ahead of the correct answer. 3 Bit Alu Verilog Example Arithmetic Logic Unit is the part of a computer that performs all arithmetic computations, such as addition and subtraction, increment. An ALU will typically take one or two input operands and output a result along with a set of status bits.

I individually tested the ripple adder and there are no problems. Arithmetic Logic Unit (ALU) An arithmetic logic unit (ALU) is combinational logic circuit which is typically used to implement a CPUs arithmetic and logic operations.

#Alu in verilog code

Here is code for the ALU: `include 'ripple_carry_adder_4.v' I.INTRODUCTION For the past decades, there were numerous of difficulties and problems. Before designing the ALU code, you should first learn the task task and. Design is implemented and verified in Verilog HDL in Xilinx 14.4. I am getting some weird results in testbecnh. Write a 4-bit ALU to implement 8 logic functions. I am implementing a 4-bit ALU using Verilog.
