CIM team in today's manufacturing environment needs to produce highest quality Equipment Integration solution for FAB within shortest time. Develop equipment integration solution has become more challenging today. Deliver a highest quality EI, which utilizes lowest equipment time for development and testing, and produce lowest defect to reduce equipment downtime, improve FAB throughput has become one of the toughest challenges of CIM Engineers today.

In order to meet such stringent requirements from the FAB, legacy SECS simulator that performs only manual trigger SECS messaging is no longer able to meet today's fast changing requirement.

Manual trigger to verify host is a very difficult, tedious, and more importantly, it is an error prone way. openSIM_lite is specifically designed to tackle these needs of host verifications. With openSIM_lite, host testing will be automated, and consistent. Well designed scenario on openSIM_lite can ensure that the EI is always tested thoroughly before it is implemented to production environment. This will be able to reduce unscheduled downtime of the production equipments
