The input (D) of the flip-flop is connected to an IPAD or an IOPAD (without using an IBUF). we will redesign the serial adder using a state table. Figure 13-12a: Serial Adder Serial Adder that adds two n-bit binary numbers Using Clocked D Flip-Flops ©2010 Cengage Learning Minimum Clock Period This page contains Verilog tutorial, Verilog Syntax, Verilog Quick Reference, PLI, modeling memory and FSM, Writing Testbenches in Verilog, Lot of Verilog Examples and Verilog in One Day Tutorial. Its storage capacity depends on the number of stages. right shifter e. CSE 205: Digital Logic Design Exercises.
