  2. DATA MOVER IN VLSIUSING L-EDIT TESTED IN DIFFERENT CAD FOR FUNCTIONALITY ASSURANCE

  3. DATA MOVER IN VLSIUSING L-EDITWHAT IS VSLI? - VSLI IS THE TECHNOLOGY THAT ALLOWS COMPANIES TO CREATE THEIR OWN CUSTOM MADE IC CHIPS. - VSLI CAN REDUCE THE SIZE OF THEIR ELECTRONIC DESIGNS. - THE CONTINUOUS USE OF IC FABRICATION TECHNOLOGY WILL LOWER THE PRODUCTION COST OF COMPLICATED DESIGNS

  4. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADOBJECTIVE The main objective was to acquire experience in asic design building a data mover with testable features to transfer data from the input to the output following a geometric algorithm. This type of design will require the use of CMOS technology and logic gate design to be fabricated into a chip

  5. WHY USE L-EDIT? • YOU CAN TEST YOUR CIRCUIT BEFORE IMPLEMENTING IT IN L-EDIT. • L-EDIT EXTRACTS THE NECESSARY CODE TO SIMULATE CIRCUITRY IN PSPICE • THE CIRCUIT IN L-EDIT IS THE FINAL LAYOUT THAT IS SENT FOR FABRICATION

  6. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADTABLE OF CONTENT Block diagram Design equations Two bit example of a data mover Timing control needed Timing chart

  27. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADFINAL APPEARANCE OF THE PROJECT IN DESING PAD

  28. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADFOUR BIT SIMULATION OF DATA MOVER IN PSPICE

  29. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADPROBLEMS ENCOUNTERED • CONTROLLER CIRCUIT NEEDED THE CLOCK ‘S RISING AND FALLING EDGE • D FLIP-FLOP HAD TO BE DESIGNED THE SMALLEST POSSIBLE TO REDUCED SPACE • PSPICE SIMULATION FILES WERE VERY LARGE AND NEEDED MANY CAPACITORS • WE HAD TO CHANGE THE DESIGN RULES IN THE DESIGN TO ADAPT IT TO A NEW TECHNOLOGY

  30. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADACCOMPLISHMENTS • I GOT INTRODUCED TO SEVERAL POWERFUL COMPUTER SOFTWARE THAT CAN SOLVE INDUSTRY PROBLEMS • A GREATER KNOWLEDGE WAS ACHIVED MANIPULATING LOGICWORKS, PSPICE, L-EDIT AND XILINX (VHDL) • I FEEL MORE CONFIDENT TO EXPLORE DIFFERENT FEATURES OF THESE SOFTWARE TO SOLVE PROBLEMS • I GAINED MUCH EXPERIENCE THAT IS REQUIRED IN THE INDUSTRY

  31. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADRECOMMENDATIONS • TEST FEASIBILITY OF DESIGN EQUATIONS • SYSTEM DESIGN IN LOGICWORKS AT GATE LEVEL • SYSTEM DESIGN AT TRANSISTOR LEVEL IN LEDIT • PSPICE SIMULATION OF TRANSISTOR LEVEL • PLACE IN DESIGN PAD FOR FINAL FABRICATION

  32. DATA MOVER IN VLSIRICARDO V. GONZALEZ. ADVISOR: VINOD B. PRASADAFTERMATH • THE TOTAL AMOUNT OF TRANSISTORS WAS OVER SIX THOUSAND • THE AMOUNT OF LINES OF PSPICE CODE WAS OVER FIVE HUNDRED LINES • IT TOOK THREE HUNDRED AND FIFTY LINES OF VHDL CODE TO GENERATE A DATA MOVER OF TWO BITS • TIME CONSUMED WAS ABOUT 200 HOURS OF DESIGN AND PROGRAMING FROM HALF OF LAST SEMESTER AND LAST SENIOR SEMESTER
