17. The Lab Report should include the following: • Experiment Title, Date, Lab Partners Names • A brief statement of the purpose of the experiment • A brief description of each experiment section • Section title • Brief procedures (in your own words) • Description of circuits designed/tested during the experiment. • Titled with a descriptive name for the circuit • Brief verbal description of the circuit's function / purpose • Circuit schematic and/or blockdiagram as appropriate • Well-documented VHDL source code (later)

18. The Lab Report should include the following: • Description of testing procedures and Results • Tables of results (with Titles and column headings) • Annotated simulation results (later with VHDL) • Other items specifically requested in the Experiment procedures. • (Be sure to include everything asked for!!) • Answers to all questions asked in the body of the experiment • A conclusion written by each group member • Both conclusions in the single report.

19. Conclusions Good Stuff • A brief description of what was accomplished in the experiment (1-3 sentences). • Identify the key learnings or most helpful parts for you personally. • What are you able to “do” or “understand” better, as a result of the lab exercise? • A brief description of how the experiment relates to other experiments and/or topics discussed in CPE 129 course lecture.

20. Conclusions: Bad Stuff • Detailed descriptions of the procedure followed during the experiment. • Detailed descriptions of the circuits designed or used during the experiment. • Comments regarding whether you liked the experiment or not. • Comments regarding how much you learned during the experiment. (“I learned a lot in this lab. …”) • Comments that state directly that the experiment’s objectives were met. Not again please…Once is enough! Not again please…Once is still enough! We hope you do! But it doesn’t belong in your Conclusions. We’re assuming that you will. “ZZZZZ”
