alu.rar_Unsigned_alu_alu quartus

This is 8 bit unsigned arithematic logical unit(ALU). This code is developed in VHDL language and compatible with any VHDL softeware like xilinx,quartus. This ALU performs addition,subtraction,multiplication,and,or,and not and pass input functions.

Sorry, it seems like you pasted an incomplete code snippet. Could you please provide me with the complete code and context so that I can understand what you're trying to achieve and help you better?
