Grading

• HW

35%

– Assignments are on the web, may be changed. If changed, I will inform you. Usually these are miniprojects. You may be asked to present them in class.

• Final Project

– You will present it in class

65%

• No exams

Grading

• Attendance at Lecture

– Not graded, but recommended.

– Attendance at Friday meetings not graded, come if you can.

• Makeup Exams

– Makeup homeworks or exams are not given .

– Project should be completed before end of the class

Homeworks

• Homeworks Require Use of VHDL

• Always you have to simulate the circuit

• You may be asked to synthesize it also.

• Mentor Graphics Tools

– contact support (cat) people

– use any lab that is available. Work at home.

– use addpkg

– We use Modelsim for simulation and LeonardoSpectrum for synthesis. Synthesis is mandatory for the project.

Slides

• My slides are based on at least 5 books, slides from

Internet and my industrial experience, on top of teaching this class since 1989. You can learn all you need if you read slides in detail.

• Not always I will cover all slides in class. In such case you have to complete reading slides for this week at home.

• You can learn a lot from previous homeworks and projects that are posted.

Honor Code

• You Are Encouraged to Collaborate With Other

Students in Projects.

• Final VHDL code for each

Homework should be done by yourself.

• In

Final Project , each file should have at the top student name of the student responsible for this part of code.

Remind the class….

• Your webpage

• List of your names with interests and experiences. Previous design projects that you have done.

– Any experience in robotics?

– Any experience in pipelined and systolic processors?

– Any experience with image processing?

– Previous VHDL or Verilog projects.

– C++ experience

– Other languages like LISP, Prolog, Basic, etc.

– I will intentionally repeat the most important parts of material or ideas. I believe in real understanding of material by students and good understanding of fundamentals is most important for me.

– You have to understand the combinational logic, flip-flops, registers, state diagrams, pipelining, ALU, etc.

– Butterfly combinational circuit from it

– Sequential controller from it

• The concepts:

– Combinational circuit

– Finite State machine

– Shifting circuits, starting from Moebius Counter. (Johnson)
