Revisiting the formal models of the IEEE 1394 link layer to highlight their development and verification.
บทคัดย่อ
This content delves into the development and verification of four formal models of the IEEE 1394 link layer, focusing on µCRL, mCRL2, LOTOS, and LNT. The article discusses the historical context, architecture, behavior, and verification of these models. It provides insights into the evolution of formal methods and the success story of detecting a deadlock error in the IEEE standard.

สถิติ
The µCRL model is quite large with 809 non-blank lines.
The mCRL2 spec is 60% shorter than the µCRL model.
The LOTOS model was revised in 2023 to reduce its volume.
The LNT model was revised to exploit the capabilities of LNT fully.
