20-sim 4C Builds

The list below shows the versions and builds of 20-sim 4C that have been released. You can check the version and build number of 20-sim 4C in the About box.

20-sim 4C 2.1

2.1.10 (17 January 2017, build 4051)

General Improvements:

  • 20-sim 4C: Allow logging on a model without finish time without demanding a finish time
  • Bachmann: replace sprinf by snprinf to prevent potential buffer overflows
  • Bachmann: add support for reading the Time_us values, the Temperature and the Usage* values from the RES module

Bug fixes:

  • 20-sim: Code generation compile error on XXExponent2 and XXExponent10 due to missing xx_logarithm constants.
  • 20-sim: C-Code: Fixed: EulerAngles_EulYXZsFromRotationMatrix accidentally did a relative transformation
  • 20-sim: C-Code template: initialize memory on zero to make sure that there a no non-initialized inputs when not connecting them in 4C.
  • 20-sim 4C: TCF cache: don't copy the cached TCF to the cache trying to overwrite itself
  • 20-sim 4C: Fixed: Connections lost when switching to the TCF from the cache folder
  • Bachmann: Taskname "aMODELNAME (1)" => "aMODELNAME_log" (prevent double task names)
  • Bachmann: Improve Bachmann task timing; only listen to the MIO_SYNC_IN signal to prevent jitter on the start times
  • Bachmann: Stop a running model does not work when the connect and compile phase are not yet green
  • Bachmann: Stopping a model stores the end values in the MCF. Restarting the model should not restore all values from the MCF. Only parameters and initialvalues should be read from the MCF. All other values are calculated by the model.
  • TS-7300: Fixed TS-ADC16 usage resulted in a compiler warning

2.1.9 (19 February 2016, build 3795)

New:

  • Bachmann: include the information from the new 20-sim 4.6 model version fields in the Bachmann module info.

General Improvements:

  • 20-sim: Register 20-sim 4C 2.1 as code generation target in 20-sim 4.6.
  • 20-sim 4C: code generation of the connection code was very slow for larger models.
  • 20-sim 4C: the connection list is now also reachable when the model is running on the target.
  • 20-sim 4C: copy the selected TCF to 20-sim 4C project cache
  • 20-sim template: optimization of the Runge Kutta 4 algorithm (less divisions and increased accuracy).
  • Bachmann: prepare the templates for hosting dynamic HTML documentation on the M1.
  • Bachmann: reduce the module loading time on Bachmann for large models.
  • Bachmann: increase the time-out for starting models on the M1.

  • Simulink: various fixes for Matlab/Simulink 2013 code.
  • 20-sim template: fix wrong formula for arctanh in C-code.
  • 20-sim template: correct the XXImpulse implementation to match the behavior of the 20-sim impulse() function.

  • Bachmann: increase the start timeout from 60 {s} to 3 minutes to allow slow tasks to start
  • Connection: The input and output connection lists can now be sorted by clicking on the column header. Default order is still the model order.

Bug fixes:
