Testing the Testers • Find another team • Test their “Working” memory • Test their “Broken” memory • Repeat in other direction • Record results in http: //goo. gl/P 3 h. FKy • You may need to power cycle in between tests.

Post Mortem • Discuss in groups of 2 or 3 groups: – What types of faults did you catch? – What did you miss? – How would you improve your testing algorithm? • What can you take advantage of? – What assumptions did you make?

Post Mortem • Look back at your work plan – How accurate was it? • Point by point, compare prediction to actual – This is not a blame session – Make more accurate predictions in the future • Send comparison to comparch 14@gmai. com – Subject [MP 2] Work Plan Comparison

Feedback • Give answers anonymously before class is over • How many hours per week are you spending on Computer Architecture outside of class? • How many should you be spending? • What can I do to make these numbers match? • What can you do?

Midterm Study Hints • Specification Documentation – Black Boxes – Do it in Human First • Counters, Comparators, Finite State Machines • Sizes of structures (Number of Gate Inputs) • Types of Flip Flops • Digital Logic – Karnaugh, Boolean Laws

Midterm Study Hints • Don’t Panic • This will be fun
