<!--
  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.
