Design and implementation of 32 bit unsigned multiplier using CLAA and CSLA

This project deals with the comparison of the VLSI design of the carry look-ahead adder (CLAA) based 32-bit unsigned integer multiplier and the VLSI design of the carry select adder (CSLA) based 32-bit unsigned integer multiplier. Both the VLSI design of multiplier multiplies two 32-bit unsigned integer values and gives a product term of 64-bit values. The CLAA based multiplier uses the delay time of 99ns for performing multiplication operation where as in CSLA based multiplier also uses nearly the same delay time for multiplication operation. But the area needed for CLAA multiplier is reduced to 31% by the CSLA based multiplier to complete the multiplication operation. These multipliers are implemented using Altera Quartus II and timing diagrams are viewed through avan waves.
