Architecture with no fracturable LUTs
- 40 nm technology
- General purpose logic block:
K = 4, N = 4
- Routing architecture: L = 4, fc_in = 0.15, Fc_out = 0.1
Details on Modelling:
Based on flagship k6_frac_N10_mem32K_40nm.xml architecture. This architecture has no fracturable LUTs nor any heterogeneous blocks.
