Challenges and Solutions
  • Challenge 1
    • Total 11 Power Buses(Include external power supply input and board internal generated)
    • Power on safety and stability make sure
  • Our Solution
    • Design test strategy for powered test
      • 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
 
 
  • Challenge 2
    • In_Line_Device_Programming
      • CPLD SVF PROGRAMMING(Device D15)
  • Our Solution
    • Using terILDP_SVF_STAPL driver to program, SVF file format (original firmware format could be .pof,.jed,etc)
 
 
  • Challenge 3
    • 1Gbit BOOT FLASH PROGRAMING(Device D5)
  • Our Solution
    • Using CC3 Flash2 drive, to implement Fast programming, approach to datasheet theoretical programming time(Device D5)
    • Spilt the firmware to resolve maximum programming timeout of tester VP card
    • Program dynamic data to memory, such as MAC address or board serial number, etc
 
 
  • Challenge 4
