Welcome to SIMBA 22.11! This version is (almost) entirely about thermal analysis. The main change is that SIMBA now supports the XML thermal library file format, currently supported by many semiconductor manufacturers. These xml files can be downloaded for free from most manufacturers' websites and describe the thermal behavior (mainly impedances and thermal losses) of their semiconductors.
Thermal description files can be imported both from the GUI and from the Python module, making it extremely easy to evaluate losses and benchmark different semiconductors. SIMBA 22.11 includes other important features such as a new dead time control model and the capability to annotate designs. If you haven’t yet, be sure to download it.
XML thermal library file format
A new option is available in the [Test Bench > Thermal Data] panel to import Thermal Library Files.
More information is available in the thermal documentation.
New Dead Time control model
A new dead time control model is added to the [Control>Discrete] library. This model delays the input signal by user-defined delays, allowing the user to model the dead time applied to semiconductor control signals.
It is now possible to annotate a design with text and various shapes using the new Annotation library.
Various Scope Improvements
- If the name is changed by the user, the new name is retained when a new simulation is run and the data is replaced.
- The order of signals in the list is now alphabetical
- The order of signals selected by the user remains when a new simulation is run and the data is replaced.
- The selection of displayed signals is simpler: one click to select/deselect.
Quality of life
In 22.11, several bugs are corrected and the general speed and stability of SIMBA is improved.
If you are interested, you can check our roadmap and a public GitHub project is available to share ideas, report bugs, and suggest new features.
