Data Mover Using Vlsi In L-Edit

Testing in different CAD for functionality assurance

Objective

The main objective is to acquire experience in asic design building a data mover with testable features to transfer data from the input to the output following a geometric algorithm. This type of design will require the use of CMOS technology and logic gate design to be fabricated into a chip
