- 1. A Project On VLSI Laboratory Name of the project: Verilog RTL for a 32-bit Carry Select Adder (CSA) To: Mr. Salahuddin Ahmed (Lecturer) By: Md. Aman Ullah Id: 021132091
- 2. An adder is a digital circuit that performs addition of numbers. In processor it is used to calculate addresses, table indices, and similar operations. It can be constructed for many numerical representations, the most common adders operate on binary numbers. ADDER MEANS???
- 3. Objectives: Write Verilog RTL for a 32-bit Carry Select Adder (CSA) that runs at 4GHz. Simulate, synthesize and physical design of that adder Directions below to create the 32-bit CSA A 4-bit Carry Look Ahead (CLA) adder Combine 8-stages of the CLA adder to create the 32-bit CSA Use 4-bit 2-to-1 mux to choose the sum from each set of CLA Use 1-bit 2-to-1 mux to select the carry for the next stage
- 4. Carry Look ahead adder: CLA is a type of adder using in digital logic. A carry look ahead adder improves speed by reducing amount of time required to determine carry bits. A carry-lookahead adder (CLA) or fast adder is a type of adder used in digital logic. A carry-lookahead adder improves speed by reducing the amount of time required to determine carry bits.

- 6. A carry-select adder is a particular way to implement an adder, which is a logic element that computes the -bit sum of two -bit numbers. The carry-select adder is simple but rather fast. Carry Select Adder

- 8. MULTIPLEXER(MUX): A multiplexer (or mux) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line
