- Usage
Usage: rttaskgen [-hV] [-i=<taskInputFile>] [-n=<taskSize>]
[-o=<outputFilePrefix>] [-r=<tasksetFileToBeReadAndPrinted>]
-h, --help Display this help message.
-i, --in=<taskInputFile> A file that contains task configurations.
-n, --size=<taskSize> The number of tasks in a task set. It is ignored
when a configuration file is specified (-i).
-o, --out=<outputFilePrefix>
A file for storing generated task sets.
-r, --read=<tasksetFileToBeReadAndPrinted>
A taskset file to be read and printed. This
option ignores other options.
-V, --version Display version info.
- Example
- A minimal use (which generates a taskset of 5 tasks):
out/bin/rttaskgen
Example output:
#TaskSet 1:
TaskSet(0.5110049327562939):
Task-3: p=950, c=98, pri=1, offset=466, f=10.53
Task-1: p=780, c=44, pri=2, offset=564, f=12.82
Task-5: p=290, c=27, pri=3, offset=181, f=34.48
Task-4: p=140, c=14, pri=4, offset=68, f=71.43
Task-2: p=120, c=19, pri=5, offset=23, f=83.33
- Use an existing configuration file to generate tasksets:
out/bin/rttaskgen -i sampleLogs/100tasks_per_condition.rttaskgen -o sampleLogs/output.tasksets
- Read and print a taskset in a readable way:
out/bin/rttaskgen -r sampleLogs/5tasks.tasksets
- Create a configuration file based on default settings:
out/bin/rttaskgen -c sampleLogs/default.rttaskgen
- Configuration File (*.rttaskgen)

- Usage
Usage: rtsim [-bhvV] -d=<simDuration> -i=<taskInputFile>
[-l=<optionLadderDiagramWidth>] -p=<schedulingPolicy>
[-o=<outputFilePathAndFormat>]...
-b, --bibs Output busy intervals as binary string.
-d, --duration=<simDuration>
Simulation duration in 0.1ms (e.g., 10 is 1ms).
-h, --help Display this help message.
-i, --in=<taskInputFile> A file that contains taskset parameters.
-l, --ladder=<optionLadderDiagramWidth>
Applicable for xlsx format. Width of a ladder
diagram.
-o, --out=<outputFilePathAndFormat>
File names (including their formats) for schedule
simulation output. The output format is
determined by the given file extension: ".
xlsx", ".txt", ".rtschedule".
-p, --policy=<schedulingPolicy>
Scheduling policy ("EDF" or "RM").
-v, --evar Enable execution time variation.
-V, --version Display version info.
