Low-cost homogeneous FPGA Architecture for QLSOFA_HD.
|
||||
|
||||
- Skywater 130 nm technology
|
||||
- General purpose logic block:
|
||||
K = 4, N = 8, fracturable 4 LUTs (can operate as one 4-LUT or two 3-LUTs with all 3 inputs shared)
|
||||
with optionally registered outputs
|
||||
- Routing architecture:
|
||||
- 10% L = 1, fc_in = 0.15, Fc_out = 0.10
|
||||
- 10% L = 2, fc_in = 0.15, Fc_out = 0.10
|
||||
- 80% L = 4, fc_in = 0.15, Fc_out = 0.10
|
||||
- 100 routing tracks per channel
