FGT-PMA-to-400G-Hard-IP-Fracture Mapping Examples

  • Example 1: If you need the st_x16_0 fracture with 16 PMAs, map it to all 16 FGT PMAs from FGT3_Quad3 through FGT0_Quad0.
  • Example 2: If you need the st_x8_1 fracture with four PMAs, map it to FGT3_Quad2 through FGT0_Quad2.
  • Example 3: If you need the st_x4_1 fracture with two PMAs, map it to FGT1_Quad3 and FGT0_Quad3.
  • Example 4: If you need the st_x1_2 fracture with one PMA, map it to FGT1_Quad3 or FGT2_Quad3.
