Final project information
VGA reference specification for those of you working on a project involving the VGA interface.
RS232-UART reference specification for those of you working on a project involving the serial interface (RS-232) and UART functionality.
Practice problems for the final exam to be held on December 14 (Monday), AVW 2328, 3:00pm - 5:00pm.
We will use these two Verilog files for our very first lab exercise:
Lab assignment, 09/16.
We will work on this assignment in the Lab on 09/16. Students are asked to work on it and develop their own solutions.
The instructor will discuss the solution towards the end of the lab session.
The following FPGA pin mapping file test_nexys2.ucf and
test Verilog file test_nexys2.v were discussed in the lab and will be useful for your designs.
The solution of this assignment is described in LA-1_sol.pdf and the Verilog implementation code is in
Lab assignment, 09/23.
RTL design and implementation of sequentlial uinsigned binary multiplier. This assignment illustrates the steps invlovled in structruing a complex design.
It also demonstrates how to separate and identify the "control" and the "datapath".
A design solution: mult-serial.v
Lab assignment, 10/07.
Design and implementation of a FIFO buffer.
A design solution: fifo1.v. Note that this design does not allow overlapping operations and that each operation takes two clock cycles.
During the lab on 10/14, we will design and test a FIFO capable of simultaneous insert/remove operations with a throughput of single clock cycle per operation.
A design solution: fifo2.v. And a test-bench file: fifo_test.v
Lab assignment, 10/28
Implementation and analysis of Finate State Machines (FSM).
Lab assignment, 11/04
Design and Implementation of Restoring and Non-Restoring division algorithms.
Lab assignment, 11/18

Course Work, Policies, and Grading
There will be 2 (two) term project assignments and 1 (one) final project assignment.
The projects will be implemented on an FPGA board. For this, students are required to purchase the
Digilent Nexys2 FPGA development board:
The version with 500K gates FPGA chip will be sufficient for this class. Note that this board is used in
other ECE classes as well.
Lab exercises and projects will be implemented using the freely available ISE WebPack software from Xilinx. It offers design capture, simulation, and synthesis functions. The software can be downloaded from
The class will have a final exam. The final exam will be based entirely on
the course material and the project assignments; it will be closed book, closed notes.
The final grade will be formed as follows:
Project 1 (Sept. 29) : 15%
Project 2 (Oct. 26) : 15%
Final Project (Dec. 18) : 35%
Lab participation : 5%
Final exam (December 14, Monday, AVW 2328, 3:00pm - 5:00pm): 30%
