Battery Utilization Analysis

Battery utilization analysis implemented in CPAchecker

Installation

For installing Battery Utilization Analysis, copy the contents from cpachecker/ to the CPAchecker project and follow the instructions for CPAchecker. Running ant should suffy for compiling the project.

Configuration

Configuration is done with a configuration file like cpachecker/config/batteryARG.properties. Battery Utilization Analysis has the following options that can be specified in the configuation file:

  • battery.c: parameter c of KiBaM, must be a real value between 0 and 1
  • battery.k: parameter k of KiBaM, must be a positive real value
  • battery.PathUpdate: the mode of updating the path, can be set to ForgetfulPathUpdate and NonforgetfulPathUpdate
  • battery.PowerConsumptionGetter: the way the analysis gets current intensity and duration, can be set to FunctionalPowerConsumptionGetter, RandomPowerConsumptionGetter, or PragmaPowerConsumptionGetter
  • FunctionalPowerConsumptionGetter takes the values from the procedure call to extern void __VERIFIER_power(double i, double t), which has to be declared in the input source file. The name of the procedure can be changed with the parameter powerConsumptionName (must be a string literal). See cpachecker/test/programs/battery/example.c for an example of use.
  • RandomPowerConsumptionGetter assigns to each CFA egde a positive normally distributed random variable with zero mean and unary variance. Boolean parameter battery.useSeed and long parameter battery.seed allow to set a specific seed for the random number generator.
  • PragmaPowerConsumptionGetter allow to specify the power consumption with pragmas of the syntax #pragma power [i|t] <VALUE> [t|i] <VALUE>. Such pragmas define power consumption of the statements in the next line.
  • Both FunctionalPowerConsumptionGetter and PragmaPowerConsumptionGetter take optional parameters battery.defaultIntensity battery.defaultDuration.

Running

Once CPAchecker is compiled together with Battery Utilization Analysis, one can run the analysis on a single file, e.g., with

./scripts/cpa.sh -config ./config/batteryARG.properties ./test/programs/battery/example.c

or on a benchmark suite, e.g., with

./scripts/benchmark.py --container ./test/test-sets/integration-battery.xml

See CPAchecker documentation for more information on the output.
