Scorecard

• October’s accomplishments:– Obtained refrigerator– MOSIS

• Completed an averager, binary-to decimal-decoder

• Last time we completed: comparator, up/down counter & seven segment displays

• October’s shortcomings:– Found error in the design of the counter—needs

debugging.

Concerns/Issues

• We still are deciding and researching ideas on the refrigerator and design.– Ex: If we can get the refrigerator to go 2°below

the desired temperature.

• Finishing MOSIS design

Conclusions

• Our team has each block of our MOSIS designed.

• Need to fix and debug MOSIS design.

• We are still on track, thanks to a good start to the project.
