full subtractor
AIM:
To verify the LAMBDA based and DRC rules of FULL SUBTRACTOR by using the back end tool and also the functionality by using CMOS transistor.
TOOLS USED:
MICROWIND3 (DSCH3/LAYOUT EDITOR)
DESCRIPTION:
A full subtractor is a combinational circuit that performs a subtraction between two bits , taking into account that a 1 may have been borrowed by a lower significant stage. This circuit has three inputs and two outputs. The three inputs denote the minuend, subtrahend, and previous borrow respectively. The two outputs represent difference and output borrow respectively.
CONCLUSION:
The LAMBDA based design rules and the functionality of the FULL SUBTRACTOR is verified by using MICROWIND 3.
