Array Index Out of Bounds Latch

HardLogic CircuitDebug

A dynamic lookup table routes hardcoded configuration values based on a 2-bit index.

Expected behavior:

| Index | DataOut | |---------|-----------| | 0 | 170 | | 1 | 187 | | 2 | 204 | | 3 | 0 |

Simulation shows DataOut = 204 when Index = 3 is applied immediately after Index = 2. The output incorrectly holds the previous state instead of defaulting to zero. Inspect the circuit and correct the fault.

Constraints

  • The design must be purely combinational.
  • Synthesis must not infer any latches.
