Information is provided here about System Design Language tools (Specification and Description Language tools, Message Sequence Chart tools and User Requirements Language tools). Some of the tools support these languages and other notations as well. The list does not intend to favour any specific supplier or tool (if you think it does - please complain). Every supplier (or even proprietary offerings) can get a reference on these pages. The purpose of this page is to enable System Design Language users to contact the suppliers and make their own judgements.

Telelogic used to provide a free "Tau SDL Standards Viewer "- browse, read and print Specification and Description Language and Message Sequence Chart (basic MSC and HMSC) documents published for viewing by standards organizations. However, it seems that both this tool  and the OG free viewer (for ObjectGeode) have been withdrawn. If anyone has information of the availability of either tool please contact the webmaster.
