2 Simplify The Complexity of Product Design Function Verification - OrCAD PSpice

3 Topic Design Challenges Production Challenges How to help developing new design faster and more stable Mechatronics integration Design Modularized simulation How to help your customer to get more powerful support

4 Design Challenges Step 1 : Make circuit design on your system Does it work? Is it stable? Step 2 : Make a Prototype in Laboratory Prepare equipment Connect system in between Does it work? Is it stable?

5 Traditional Design Flow Schematic drawing in your design Make prototype Measurement in Laboratory Repeatedly try and error How long? Cost?

6 A Virtual Laboratory OrCAD PSpice Curve Tracer OrCAD PSpice Statistical Analysis ayss Measurement Expression Function Generator Logical Analyzer ay Oscilloscope Network Analyzer Spectrum Analyzer Power Supply

7 Virtual Design Flow Schematic drawing Simulate and results confirmation PCB layout Manufacture

8 A Quality Analysis Laboratory Mass Production Issues Complexity Stability Components Specification Cost

9 Mass Production Challenges Prototype It works It is stable How about Mass Production? Parts specification? Tolerance Temperature issue Is it stable?

10 Enhance Circuit Design Stability Is simple best? Using Parts with high accuracy and stable specification to improve stability. Enhance stability with compensate circuit design. Using other structure design.

11 Design Flow for Mass Production Get a standard system design from origin Measure and find out better structure Include tolerance and temperature parameters Parametric Sweep Worst Case Analysis Monte Carlo Analysis ( Yield )

12 Parametric Sweep Make sure structure and parts are good for design.

13 Worst Case Analysis Effects of Components Tolerance Limitation on Worstp Case Analysis

14 Monte Carlo Analysis

15 Mechatronics Integration Design Automotive Safety System Passive mode:abs Airbag Reversing radar Active mode:dstc, ROPS, EBD, CWFAB, PDFAB, DAC, LDW
