Zetav is a tool for verification of systems specified in RT-Logic language.
Verif is a tool for verification and computation trace analysis of systems described using the Modechart formalism. It can also generate a set of restricted RT-Logic formulae from a Modechart specification which can be used in Zetav.
With default configuration file write the system specification (SP) to the sp-formulas.in file and the checked property (security assertion, SA) to the sa-formulas.in file. Launch zetav-verifier.exe to begin the verification.
With the default configuration example files and outputs are load/stored to archive root directory. But using file-browser you are free to select any needed location. To begin launch run.bat (windows) or run.sh (linux / unix). Select Modechart designer and create Modechart model or load it from file.
As the night came to a close, Rohan and Aishwarya looked into each other's eyes, knowing that this was just the beginning of their beautiful journey together. They knew that their love would only grow stronger with time, and they couldn't wait to see what the future held for them.
The couple spent the evening enjoying a romantic dinner, watching the sunset, and getting to know each other better. They talked about their dreams, aspirations, and hopes for their future together.
I hope you enjoyed the story!
Finally, they arrived at the resort, a serene oasis in the midst of the bustling city. They were greeted with a warm welcome of flowers and a sweet-smelling garland, which Aishwarya's mother had specially prepared for them.
As the night wore on, they decided to take a walk around the resort, enjoying the cool breeze and the peaceful atmosphere. They strolled hand in hand, taking in the sights and sounds of the resort, and sharing sweet kisses under the stars. As the night came to a close, Rohan
As they returned to their suite, Rohan took Aishwarya's hand and led her to the balcony, where they sat together, watching the stars twinkling above. They talked about their first night together, and how they wanted to make it a special one.
The rest of the night was a blur of romance, laughter, and happiness. They enjoyed each other's company, and their love for each other only grew stronger with every passing moment. They talked about their dreams, aspirations, and hopes
As they entered their suite, Rohan was struck by its beauty. The room was decorated with candles, flowers, and a stunning view of the city skyline. Aishwarya squealed with delight as she saw the romantic setup, and Rohan couldn't help but smile at her enthusiasm.
The sun had just set over the bustling streets of Chennai, casting a warm orange glow over the city. Rohan and Aishwarya, a newlywed couple from a traditional South Indian family, had just exchanged their vows in a beautiful temple ceremony. They were now on their way to their honeymoon suite, a luxurious resort on the outskirts of the city. They were greeted with a warm welcome of
As they drove through the crowded streets, Rohan couldn't take his eyes off Aishwarya, who looked stunning in her red silk saree, her hair adorned with intricate flowers and her eyes shining with happiness. He felt like the luckiest man alive to have her by his side.
The Zetav verifier expects the input RRTL formulae to be in the following form:
<rrtlformula> : <formula> [ CONNECTIVE <formula> ] ... <formula> : <predicate> | NOT <formula> | <quantifiedvars> <formula> | ( <formula> ) <predicate> : <function> PRED_SYMB <function> <function> : <function> FUNC_SYMB <function> | @( ACTION_TYPE ACTION , term ) | CONSTANT <quantifiedvars> : QUANTIFIER VARIABLE [ QUANTIFIER VARIABLE ] ...Where predicate symbols (PRED_SYMB) could be inequality operators <, =<, =, >=, >, function symbols (FUNC_SYMB) could be basic + and - operators, action type (ACTION_TYPE) could be starting action (^), stop action ($), transition action (%) and external action (#). Quantifier symbols (QUANTIFIER) could be either an universal quantifier (forall, V) or an existential quantifier (exists, E). Connectives (CONNECTIVE) could be conjunction (and, &, /\), disjunction (or, |, \/), or implication (imply, ->). All variables (VARIABLE) must start with a lower case letter and all actions (ACTION) with an upper case letter. Constants (CONSTANT) could be positive or negative number. RRTL formulae in the input file must be separated using semicolon (;).
V t V u (
( @(% TrainApproach, t) + 45 =< @(% Crossing, u) /\
@(% Crossing, u) < @(% TrainApproach, t) + 60
)
->
( @($ Downgate, t) =< @(% Crossing, u) /\
@(% Crossing, u) =< @($ Downgate, t) + 45
)
)
Verif tool does not deal with direct input. Examples are load from files with extension MCH. Those files are in XML and describes model modes structure and transition between modes. There is no need to directly modify those files. But in some cases it is possible to make some small changes manualy or generate Modechart models in another tool.
