-------------------------------------------------- State Graph Manipulators (SGM) New GUI Version 1.2 Released (Solaris OS)!!! New Interactive Version 1.1 Released (Linux OS)!!! -------------------------------------------------- "http://www.iis.sinica.edu.tw/~eric/sgm/" -------------------------------------------------- State Graph Manipulators (SGM) is a high-level state-graph manipulation tool for verification non-experts as well as experts. After the release of SGM v1.1 which was a more stable version, we are now releasing SGM v1.2 which has a Graphical User Interface (GUI) that allows more logical and flexible manipulation of state-graphs. SGM v1.2 with GUI is now ready for downloading. This version provides both three interfaces: batch, interactive, and graphical user interface. "Important NOTE" Those who downloaded SGM v1.1 recently are strongly advised to download SGM v1.2 which provides not only a GUI, but also removes some program bugs. Changes in v1.2 from v1.1 (1) A Graphical User Interface (GUI) provided for a more user-friendly verification environment as well as for demonstrating how state-graphs can be reduced by different manipulators (reduction techniques). The SGM GUI provides not only all the functionalities that were present in the interactive/batch modes, but also some new facilities like graph viewing, renaming, printing, saving, and input file editing, etc. On-line help is provided in the GUI. (2) Memory usage further reduced to 1/10th of that originally required in SGM v1.0 and 4/5th of that required in SGM v1.1. Memory leaks removed using Purify, a commercial program debugging tool from Rational Software. (3) All 5 application examples that were included with v1.1 distribution, can now be directly loaded into the GUI by just some clicks of a mouse button. (a) Fischer's Mutual Exclusion Protocol, (b) CSMA/CD Protocol, (c) Token Ring Network, (d) PATHO OS Priority-Based Task Execution, and (e) Bus Arbiter. (4) User manual updated to version 1.2. (5) Further programming bugs/errors fixed. Visit URL: "http://www.iis.sinica.edu.tw/~eric/sgm/" to download SGM v1.2. SGM web site completely renewed for easier download and access.
