DiscreteComponents

This is the documentation for the DiscreteComponents library. Here you will find the documentation for the various definitions contained in DiscreteComponents.

Note that this documentation is automatically generated primarily from the doc strings and metadata associated with those definitions.

Components

• ClockPropagator - EXPERIMENTAL: a way to connect clocks of two signals but not their values.
• DummyDynamics - INTERNAL: Dummy dynamics to add some time dependent state, such that ModelingToolkit can understand that the problem is time dependent.
• Examples.AccumulatorGraphical - An accumulator built using block diagram components.
• Examples.AccumulatorSyntactic - An accumulator written using clock syntax directly.
• Examples.DirectDerivative
• Examples.DirectIntegral
• Examples.IncreasingFrequencyCosineSource
• Examples.IntegratorFEwInitial
• Examples.IntegratorFEwInitialSimpler
• Examples.IsNaN
• Examples.LessThan
• Examples.ResetValueTracker
• Examples.SimpleDiscreteIntegrator
• Examples.Switch
• Examples.TestZeroCrossingClock - Test component that validates the ZeroCrossingClock component.
• LastValue - Gets the last defined value of u to place on y, on the clock of y.
• NDelay - A delay block that delays its input by n timesteps.
• PeriodicClock - A periodic clock that ticks once every dt time units.
• PeriodicSampler - Sample a continuous signal y at a periodic interval dt, creating a clocked signal y.
• SampleTimeSource - Outputs the time since the last sample on the clock that is connected to y.
• Sampler - Clock-agnostic sampler block.
• UnitDelay - A unit delay that outputs the input signal delayed by one sample (z@(-1)).
• UnitDifference - A unit difference block that computes y[n] = u[n] - u[n-1].
• ZeroCrossingClock - A zero-crossing clock that ticks once every time the input signal crosses zero.
• ZeroOrderHold - A zero-order hold operator that maps a clocked signal u to a continuous time signal y.

Analyses

• Examples.AccumulatorDemoAnalysis

Examples

• Examples.AccumulatorDemo - Test harness that samples a sine wave and accumulates it using both accumulator types.
• Examples.IfLiftBug - This component shows some bugs in MTK's IfLifting pass.
• Examples.PowerHeptagonBug - This errors because Heptagon does not like the character ^ in a function name,
• Examples.ZOHBug - The output of the ZeroOrderHold block looks flat but it is actually not.

Tests

• Examples.IntegratorFEwInitialTest
• Examples.TestClockPropagator
• Examples.TestNDelay - Test component that validates the NDelay component.
• Examples.TestPeriodicClock - Test component that validates the PeriodicClock component.
• Examples.TestUnitDelay - Test component that validates the UnitDelay component.
• Examples.TestUnitDifference - Test component that validates the UnitDifference block by computing the discrete difference of a sine wave.
