These are the release notes of FSAP/NuSMV-SA 1.2.1.
Old Release Notes
This release of the FSAP platform has several improvements. Hereafter there is the list of these improvements:
Quantification: probability calculated for Top Level Events. Assuming the user defines the probability for individual failure modes and/or failure sets the probability for the TLE and all intermediate events will be calculated and shown in the fault tree (using FSAP's fault tree displayer or FaultTree+).
Failset Exports: failure sets defined in FSAP can be exported in an XML format which conforms to the format used within the ISAAC project.
Empty (or 'true' and 'false') fault trees can be generated. So fault trees can be generated even when no failure variables are available.
An option 'NR_FAILURES' can be used when computing an FMEA table. This option defines the number of failures shown in the FMEA table which lead to a given message (i.e. if NR_FAILURES is set to '3' then the FMEA computation will return all combinations or three failures or less which lead to Message X).
Imported Failure Sets were mistakenly identified as Failure Modes, leading to FSAP crashing. Imported FS are now handled correctly. (Windows only).
The main features of the FSAP/NuSMV-SA platform are:
Support for SAT XML format
Full support to GFML (Generic Failure Mode Library): failure modes can be defined in the GFML, used from FSAP, and automatically injected into the model.
Full support to GSRL (Generic Safety Requirements Library): safety patterns can be defined in the GSRL, used from FSAP, and loaded at the user request.
Analysis task manager
Automatic model extension.
Possibility of defining custom failures directly into the system model.
Possibility of defining or importing custom failure sets, comprising several failure modes, and including them directly into the system model.
Possibility of defining messages for fault isolation or fault detection analysis.
Possibility of grouping messages into message classes for fault isolation or fault detection analysis.
Highlighting of changes: parts of the SAT that are changed appear in red.
Quick search of Safety Requirements and Failure Modes.
Integration with NuSMV-SA.
Result Displayer, for accessing in an integrated way all the results of the analyses.
Fault Tree Displayer, that reads files in Fault Tree Plus tabular format.
Viewer of traces in tabular and graphical form (through GnuPlot).
Monotonic and non-monotonic fault tree construction
Generation of traces for each minimal cut set of a fault tree
Possibility of choosing different model checker engine: either BDD or SAT-based model checker
Ordering analysis on minimal cut sets
Implementation of Failure Mode and Effect Analysis (FMEA) producing tab-delimited text output
Construction of fault trees, generation of traces, ordering analysis, simulation, and verification of properties are integrated with FSAP
Calculation of the probability for a Top Level Event of a Fault Tree given the probability of the basic events.
All NuSMV2 commands available from textual interface
Win32: MS Windows XP
Lin: Linux RedHat 9.0.
In order to correctly run FSAP/NuSMV-SA, the following tools are needed. m4 and Expat are included in the distribution (in the case of Windows, for Linux they should be installed already - m4 at least) but Gnuplot must be downloaded separately:
Gnuplot (for graphing counter examples).
Windows Platforms. Installation procedure on Windows platform uses the standard approach.
Download the relevant FSAP-Setup.exe file from the Download page.
Double click on FSAP-Setup.exe and follow the instructions.
Unix Platforms. The only *nix platform for which we provide pre-compiled binaries is Red Hat Linux. Compiled versions for other *nix like systems are available on demand.
Download and install Expat if necessary.
Download the relevant .zip file from the Download page.
Unzip the package in a directory of your choice.
