--- res: bibo_abstract: - We describe a new implementation of HYTECH, a symbolic model checker for hybrid systems. Given a parametric description of an embedded system as a collection of communicating automata, HYTECH automatically computes the conditions on the parameters under which the system satisfies its safety and timing requirements. While the original HYTECH prototype was based on the symbolic algebra tool Mathematica, the new implementation is written in C++ and builds on geometric algorithms instead of formula manipulation. The new HYTECH offers a cleaner and more expressive input language, greater portability, superior performance (typically two to three orders of magnitude), and new features such as diagnostic error-trace generation. We illustrate the effectiveness of the new implementation by applying HYTECH to the automatic parametric analysis of the generic railroad crossing benchmark problem and to an active structure control algorithm@eng bibo_authorlist: - foaf_Person: foaf_givenName: Thomas A foaf_name: Henzinger, Thomas A foaf_surname: Henzinger foaf_workInfoHomepage: http://www.librecat.org/personId=40876CD8-F248-11E8-B48F-1D18A9856A87 orcid: 0000−0002−2985−7724 - foaf_Person: foaf_givenName: Pei foaf_name: Ho, Pei foaf_surname: Ho - foaf_Person: foaf_givenName: Howard foaf_name: Wong Toi, Howard foaf_surname: Wong Toi bibo_doi: '10.1109/REAL.1995.495196 ' dct_date: 1995^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0818673370 dct_language: eng dct_publisher: IEEE@ dct_title: 'HyTech: The next generation@' ...
