Try MultiSim it is free usually with tech. books.

Try Simio. Simio is a SImulation Modeling framework based on Intelligent Objects. This may be a bit different than other simulation packages that you may be familiar with, even those that market themselves as object oriented. Simio is designed from the ground up to support the object modeling paradigm; however it also supports the seamless use of multiple modeling paradigms including a process orientation and event orientation. It also fully supports both discrete and continuous systems, along with large scale applications based on agent-based modeling. These modeling paradigms can be freely mixed within a single model. http://www.simio.biz/
