Translating Erlang to /spl mu/CRL

The language Erlang has been developed by Ericsson to implement large switching systems. Erlang is nowadays used by several companies for complex embedded systems. The language /spl mu/CRL is a process algebra with data. Several verification tools are available for /spl mu/CRL and other process algebras, including a tool to create labelled transition systems from /spl mu/CRL specifications. By having a translation from Erlang to /spl mu/CRL we can apply the verification tools for process algebras and labelled transition systems to industrial code. The translation is aware of the major design component in the switching software. This knowledge is used to ensure that the size of the labelled transition system generated by the tools is smaller than with a naive translation.
