对于使用永不声明的验证(使用 ispin),我得到depth reached
的输出大于状态数和转换数,例如:
Full statespace search for:
never claim + (REQ5)
assertion violations + (if within scope of claim)
cycle checks - (disabled by -DSAFETY)
invalid end states - (disabled by never claim)
State-vector 60 byte, depth reached 87, errors: 1
41 states, stored
10 states, matched
51 transitions (= stored+matched)
9 atomic steps
hash conflicts: 0 (resolved)
我觉得这有点不直观。某处是否有“深度达到”语义的精确描述(比pan 的输出格式描述更彻底)?或许的意义
最长的深度优先搜索路径包含 87 个转换
不是指 51 个转移,而是指由永不主张组成的系统自动机的转移?
