QuestaSim code coverage report XML, as written by 'vcover report -xml -details' or 'coverage report -xml'. Questa states neither a namespace nor a format version. The schema is built from three sources: * a report of Questa 2026.2 written with 'vcover report -xml -details -code bcesf': root attributes 'questa_version' and 'command'; 'lines', 'byInstance', 'instanceData' with 'sourceTable', 'fileMap', the statistics 'branches', 'states', 'transitions' and 'statements' - in this order, which contradicts the DTD -, 'stmt', 'if'/'ielem', 'case'/'celem', and the states and transitions of finite state machines, 'state'/'trans', which name no file number; * the Questa User's Manual and a report of Questa 2023.3 (by design unit): 'byDU', 'DuData'; * ModelSim's DTD 'covreport.dtd' for the elements no Questa sample shows yet: the summary records, 'fileData', the details of conditions, expressions and toggles. A scope's 'sourceTable' comes first; its statistics and details follow in any order, except a finite state machine's: 'states', 'transitions', then each 'state' and each 'trans'. Functional coverage reports ('functional_coverage_report') aren't covered.
