Microcode Test Sequences

Concept

**Microcode test sequences** are generated instruction streams used in microprocessor verification to exercise opcode behavior and instruction-attribute combinations. As processor designs have increased in complexity, verification has shifted away from hand-written directed tests toward automated random test generators that can cover stimulus spaces more efficiently.[^1]
