      • Correct power supply point and power up sequence
      • Crucial Fixture circuit and wiring for power up (current flow capability and power sense feedback control consideration)
    • Design debug strategy
      • How to safely turn on each power
      • How to eliminate noise coming from fixture
 
 
  • 挑戰二
    • In_Line_Device_Programming
      • CPLD SVF PROGRAMMING(Device D15)
  • 我們的方案
    • Using terILDP_SVF_STAPL driver to program, SVF file format (original firmware format could be .pof,.jed,etc)
 
 
  • 挑戰三
