ELECTRONICS TELECOM
Capstone Design Document
• Single point of information for stakeholders• Built over time – iterative process• Updated through revisions• Maintained in notebook – available at all meetings• Elements
– Problem statement– Problem statement– Functional requirements– Conceptual block diagram– Performance requirements– Technology survey assessment– Detailed functional block diagram– Deliverables– Milestones– Gantt Chart– Test Matrix
ELECTRONICS TELECOM
Problem Statement
• High-level statement of system need
• Example:
– Locate and display the physical position of a – Locate and display the physical position of a mobile device
ELECTRONICS TELECOM
Functional Requirements
– Battery operated and replaceable– Stand-alone, self-contained intelligent unit– attached to anything– Size– Weight– Simple user interface with Prog/diagnostic port– Locates itself anywhere on earth with lat-long with elevation
output– Weather-proof to work in any existing earth-based condition– Store and forward operation– Communicate position via COTS wireless network in pseudo
real-time– Display position information from multiple devices using GIS-
based GUI
ELECTRONICS TELECOM
Conceptual Block Diagram
• Depicts requirements in pictorial diagram format
• Supports interaction, discussion and development of performance requirementsdevelopment of performance requirements
• Include all elements of system
• May require multiple diagrams
• Example

Performance Requirements
• Defines needs for each subsystem to be developed
• Expands on each of the Functional RequirementsRequirements
• Used to transition from Conceptual to Functional block diagram
• Examples
ELECTRONICS TELECOM
Performance Requirements
– Battery operated• Internal• Replaceable• 24 hours of continuous operation – determines amp-hour rating• External recharge of battery • Voltage = > 3.0Vunregulated input• etc
– Stand-alone, self-contained intelligent unit– Stand-alone, self-contained intelligent unit• Processing power
– 8 or 16-bit processor– programming interface– DI/O – 8 bits– No analog
• Memory– program– storage – 100 messages not non-volatile memory
• Interfaces– User I/F – serial >9.6Kbps– Location Det – serial >9.6Kbps– Wireless Comm – TCP/IP >56Kbps
• Etc
ELECTRONICS TELECOM
Performance Requirements
– Attach to wood or metal or cardboard devices that exceed 2x2x2 feet • Remove without destroying• Magnetic or screw mount• Peel-off tape
– Size• Thickness must be less than 2 inches• Length and width should be less than 5 inches
– Weight– Weight– Simple user interface with Prog/diagnostic port– Locates itself anywhere on earth with lat-long output– Weather-proof to work in any existing earth-based condition– Store and forward operation– Communicate position via COTS wireless network in pseudo real-time– Display position information from multiple devices using GIS-based GUI– Cost – Unit 1 fabrication
ELECTRONICS TELECOM
Technology Survey Assessment
– Potential solution – minimum of three for each functional requirement
– Pros and cons – related to performance requirements
– Selection – justify– Selection – justify
– Example: Locates itself• GPS
• Inertial Navigation
• StarVision Module

Deliverables
• Something of “Value” to the customer• Interim
– Provided to stakeholders during the project execution
• Final– Provided at the completion of the project
• Description• Description– Detailed
• Timeline– Graphic of due dates for each deliverable and status updated
weekly
• Example:Schematics will be created and submitted for the remote monitor, expansion module,
power inverter, and peripheral interface board. They will be created with the schematic
capture program in Multisim. Schematics will be printed on 8.5 x 11 inch sheets of paper and
may employ subcircuits to achieve this format. Subcircuits will have input and output labels as
well as a meaningful subcircuit title. All symbols created while developing the circuit will be
submitted via the Multisim user database in the softcopy format of the schematic. Additionally,
symbols from OI Analytical’s current library may be used to aid schematic development. This
deliverable will be submitted in both softcopy and hardcopy format. Hardcopy printouts will be
printed in landscape orientation.

Deliverable Timeline
ELECTRONICS TELECOM
Milestones
• An “Event” that indicates significant progress
• Description– Detailed
• Timeline– Graphic of due dates for each milestone and status updated – Graphic of due dates for each milestone and status updated
weekly
• Example:The first milestone is the approval of the completed test plan. The test plan will define
the parameters for passing or failing each piece of hardware and software. It will also set the
structure for collecting test data. Extensive testing will guarantee that the prototype meets all requirements and will ensure the project’s success. This milestone will be completed by
September 7, 2009.DEMONSTRATIONS
