Design Review Checklist

CS-EE 480 Fall 2006 Directions

 For each major checklist section (General, Software, Digital, Integrated Circuits, Control Systems), o Determine what collateral material will be prepared for the meeting and sent to the Industry Representative. Bring to the meeting all documentation needed to explain and justify your design decisions. o Review each item in the checklist for applicability and mark that field with a checkmark ().

NOTE: Not all items will be applicable to every project. If an item is not applicable, you may wish to enter an explanation in the comment field.

 Add additional applicable checklist items using the Other field.  Review each applicable item in the checklist and verify that it has been met by your design. Mark the checked field with a checkmark ().

NOTE: An applicable item can only be verified or not verified (Boolean). You cannot have an item that is one-half verified.

 Use the comment field to add information that elaborates on your decision to mark or not mark an item as checked.

Follow-Up

 Prepare meeting minutes of your Design Review and post them along with the completed checklist on your web site.  Your design review is: Approved, Conditionally Approved, or Not Approved.

Approved: all checklist items verified. Conditional: one or two minor checklist items not verified (but easily fixed). Not Approved: major or several minor checklist items not verified.

 Any applicable item not checked off may be grounds for not approving the design.  All applicable items not checked off require an Action Item with responsible individual and due date.

Checklist

1. Do "paper" digital chip circuit block diagram design. (Note: only 40 pins are available including power/ground and that this is a 5V CMOS technology. Do synchronous design only !). 2. Do "paper" digital chip circuit design (as much as possible). 3. Do B2Logic digital chip circuit simulation using B2Logic/BLT software. 4. Do design review/release of finalized B2Logic digital circuit design. 5. Create initial .edf file in B2Logic/BLT and email to Dr. Osterberg asap in early November. He will then run a preliminary BLT and SPR in L- EDIT. If chip properly fits within 2.2mm x 2.2mm (or 4.6mm x 4.7mm) standard padframe, then Dr. Osterberg will give you the greenlight to proceed to Step 6. If chip does not fit in one of these padframes, then he will return .edf file to you with suggestion on how many gates to remove in order to reduce size of chip and then GOTO step 3.

6. Create final .edf file and email to Dr. Osterberg who will then re- run BLT and SPR in L-EDIT. Again, if chip properly fits within 2.2mm x 2.2mm (or 4.6mm x 4.7mm) standard padframe (which, of course, it sould due to Step 5) then Dr. Osterberg will, himself, go on to create .cif file and send onto MOSIS. Of course, if chip does not fit in one of these padframes, then he will return .edf file to you with suggestion on how many gates to remove in order to reduce size of chip. GOTO Step 3. Again, note that the odds of failure here is low due to Step 5. 7. Decide on how you wish to build your discreet macro-model (i.e.: CPLD, wire-wrap, plug-and-go protoboard, etc). Note that I suggest CPLD, but it's up to you. 8. Order your macro-model parts including devices, boards, wire- wrap gun, wire-wrap wire, etc. 9. Build and debug your macro- model. 10. Build and debug your overall project system using your macro- model. 11. Receive MOSIS chip. 12. Replace macro-model with chip in system and verify functionality (or not). 13. If chip works, hurray. If not, then just use macro- model in your system and demo with it.
