The new version of SimOne 2.6 Beta is now available
New Features in SimOne
User Feedback
The feedback with a message to the developers can now be sent from inside SimOne. With the Help→Feedback menu entry “Contact developer” window is opened.
At the window there are optional fields for the sender email, name and the message subject. The message text cannot be left blanc. If the message type is Question, the email to send the response must be provided too.
The message types are:
- Question,
- Suggestion,
- Bug,
- Interface issue or
- Other.
Additional information can be send:
- Scheme (or netlist),
- Current SimOne view screenshot (without Contact developer window),
- System information,
- Any other file.
The sent messages are stored in the history. To view them click the Message history button.
Touchstone model and N-port devices
SimOne now supports N-port components, specified with S-, Z- and Y-parameters.
The parameters can be set either as expressions or as Touchstone files.
N-ports can be placed to the schematic either
- as a primitive (toolbar icons
) or - a component from included libraries of Touchstone-models:
A new property is introduced for Laplace sources and N-ports: MaxF. It defines the Inverse Fourier Transform step applied to the specified element (or model) in simulations. Note: this doesn't define the element itself, but only the behaviour of computational algorithms.
Graphs
Graphs in AC analysis can be displayed on the Smith chart.
