This invention relates to the field of
semiconductor manufacturing virtual
simulation technology, and discloses a method and
system for simulating hardware communication protocols. This scheme achieves asynchronous decoupled communication between AMHS services and
machine services through message queues (such as MQ), replacing the traditional hardware parallel I / O
interaction method. The core includes: defining a protocol format for packaging multi-bit signals (such as 16-bit binary numbers); encoding signals such as VALID and CS_0 into
single sequence messages (such as hexadecimal "4030"); maintaining a predefined sequence
list (indexing corresponding communication steps) and the latest sequence status; and verifying whether a new message matches the expected sequence. If it matches, the status is updated and the process is advanced; otherwise, it is rejected and reset. The
system includes AMHS services,
machine services,
message queue components, a storage module, and a
verification module. This invention solves the problems of service dependency, bandwidth waste, and complex sequence
verification in virtual scenarios, significantly improving
simulation efficiency and realism, and is suitable for the
interactive simulation of AMHS and
machine interactions in
semiconductor FAB plants.
