42. Equality Operators

Design a circuit that detects whether a 2-bit input matches the pattern 2'bx1. Implement two versions using different equality operators.

Requirements

• Module: x_detector
• Inputs: a[1:0]
• Outputs:
  • eq_logic — result of a == 2'bx1 (logical equality)
  • eq_case — result of a === 2'bx1 (case equality)
