STATUS

• Design Proposal (Done)
• Architecture (Done)
• Size Estimates/Floorplan/Verilog (88 -
  comb/Wallace alterations)
• Gate Level Design (85 - comb/Wallace
  alterations)
• Component Layout (Done - However, continue to
  optimize)
• To Be Done
• Complete layout of functional blocks
• Wallace Tree Multiplier, etc.
• Schematic
• Make remaining adjustments for comb/Wallace
• Verification
• Test for adjusted blocks

3
DESIGN DECISIONS

• Comb
• Made Adjustment for functionality in Real number
  domain.
• Wallace Tree Multiplier
• Currently implementing the basic Wallace
• Booth Recoding intended next

4
DESIGN DECISIONS

• Porosity of Basic Components
• Using only Metal 1 and Poly in order to ease
  global routing
• Use Metal one AND Metal 2 for basic components
• Imaginary Numbers
• Working on soft IP while verifying current design
  has tossed off all old complex components.

PROBLEMS QUESTIONS

• Booth Recoding
• Still walking through
• Problem Timing issues with top level design.
  Havent tackled yet (fixing lower blocks to avoid
  complications)
• scientific method only test one variable at a
  time
