What’s new in 25.6

We are sure you know how convenient it is to upload files to Engee by simply dragging and dropping into the window. file browser from your File Explorer (or Finder). Now we have implemented the ability to drag an entire folder with files without the need for additional archiving. Well, that’s great!

The work with the blocks that transmit has been very powerfully redesigned ( Goto) and accept ( From) signals to avoid dragging lines through the entire model, and also store data ( Data Store Memory). Now you can add receivers and sources to the canvas by simply pulling them out of the parent block.

We have also implemented a tool that analyzes related blocks and makes it possible to quickly navigate them. In addition, it will warn you if conflicting receivers are added by mistake or duplicates are present.

Large own block libraries They often require a complex nested structure and hierarchy. Previously, to create a subcategory, you had to create subsystem without inputs and outputs and already put the necessary block inside it. But it was still one level of hierarchy in the library.

Now, from various library files (.nglib), you can assemble a multi-level library with a configurable hierarchy. To do this, go to the folder with the library you are creating (don’t forget to add it to path) add the file engee_library.toml and specify the structure and composition of the library at its various levels. A clear example is shown in the screenshot below.:

We have done a lot of work on the processing, optimization and acceleration of the software core of the Engee modeling environment. This has affected many aspects of the development environment and the launch of models, but a special effect is noticeable on the speed of command execution. program management. Amazingly, we managed to speed up the startup time, build time, parameter definition, etc. to 1000 times or more! Try it yourself, you will definitely notice the difference! Software control is now performed almost instantly.

The physical variables recording selection menu has been redesigned, it has become clearer and more convenient, and a new feature has appeared — the ability to record all physical variables at once, not just for selected blocks. You can now open the tool from the same menu. Physical variables .

Added a new element to block mask editor — A Button. Now you can run calculations or simulations by clicking on this element directly from your custom block or subsystem.

Previously, you could only determine the end time of a simulation by a specific number. Now we have implemented for you the possibility to define it with a variable or a mathematical expression. This can be useful, for example, to finish executing the model at the end of the experimental data, or to link it to the sampling rate of the model. This feature also opens up additional automation options.

Previously, there was a possible situation when model simulations ended with an error, but no warnings were displayed and it seemed that the process was completed successfully. Now we’ve fixed that and added new messages to the menu. model diagnostics , which will display the corresponding warning and the time for which the simulation was terminated in an emergency.

Added an informational warning that you are trying to enter a busy value for ports finite automata when renaming them.

The app "Evaluation of amplifier parameters " simulates nonlinear power amplifiers using data from real or synthesized signals. It allows you to take into account the expansion of the spectrum and interference in neighboring channels, as well as apply digital signal pre-distortion (DPD) to minimize distortion.

The purpose of DPD is to distort the input signal so that after passing through the amplifier, the resulting signal is close to ideal. The application supports various algorithms for calculating DPD parameters, such as RLS, LMS, NLMS, RPEM and regularized RLS, as well as model architectures, including P, MP and GMP. The choice of architecture depends on the estimation of the normalized mean square error (NMSE) of the amplifier model.

Digital preconfigurements provide:

The application helps to adapt wireless communication systems to specific operating conditions, effectively using power amplifiers.
