Clocks TODO

[baggepinnen]

• Hook up codegen when ODEFunction is called
• Do something with all the data saved by discrete-time partitions
• Clean up old code generation for discrete-time systems
  • rm old discrete system #2413
• Get rid of old, ill-defined discrete operators
  • rm old discrete system #2413
• Set initial condition for discrete variables with a sane syntax
• code generation with more than one discrete-time partition
• add tests for multiple clock rates
• Handle negative shifts, several broken discrete-time examples #2359
• Store solution to discrete-time partitions and make it accesible through idxs keyword
• handle plotting of discrete-time data with steppost + marker appearance
• Specification of data types of state variables and parameters in the MTK model, e.g., Int, Float64 etc. This type has to be configurable by the user instantiating a block, e.g., the user can select whether an integer variable is Int64 / Int32 etc., @mtkmodel does not handle specification of variable type #2491
• Introduce Sample and Hold blocks in MTKstdlib, WIP: discrete-time components ModelingToolkitStandardLibrary.jl#242
• Introduce super and sub sampling add ClockChange operator #2744
• Introduce Clock block that can be connected to discrete-time components to associate them with a clock
• Handle calls to sampletime in equations that have InferredDiscrete time domain. This should use a connected clock if available, otherwise set the domain to inferred. add sampletime operator #2690
• Test discrete-time partitions that include both positive and negative shifts
• Add documentation
  • Mention implicit (k) index for non-indexed variables
  • Nail down the semantics of the shift index w.r.t. initial conditions. The simulation starts at shift index k, and the initial condition is all indices less than k.
  • add docs for sampled-data systems #2410
• Add tutorials
• Missing initialization of discrete-to-continuous communication parameter #2356
• Test inversion of discrete-time model.
