Using XML to implement Abstraction for Model Checking

Model Checking has become one of the most powerful meth-ods for automatic verification of software systems. How-ever it is widely accepted that this technique is only usable when the behavior of the system to be analyzed is given by small models, in order to avoid the state explosion problem. The paper presents oSPIN, an XML-based tool for obtaining abstract versions from a given model written in PHOMELA, which can be verified with the model checker SPIN. This tool follows the theoretical basis presented in [9]
