Version 5.8 released

[QucsStudio]

The long-awaited, new version is available in the download section. Note that the application name changed to uSimmics in order to clearly distinguish it from the Qucs projects. This is a major release with many, many improvements, new features and bugfixes.
And as always: Thanks a lot to all supporters! This release would not have been possible without you.
Please consider to help keeping this project alive by supporting it.

Congratulations and thanks a lot for your effort!

Is ther a change log we could check somewhere?

[Carsten]

Thank you very much for making this possible!

Changelog would be nice.

Just saw, Qucs is not using another pcb layout tool.

Thank you very much for all the effort you have put into uSimmics!

 

Warm regards,

Daniel.

function rtoz() is no longer defined. Is that a bug or intentional?

I remember using it once.

ztor() still exists

[QucsStudio]

Yes, this is intentional. stoz() does the same job, so please use this function. ztor() is still needed and thus, does still exist.

Hi “QucsStudio”,

 

uSimmics v5.8 really made a major step in usability:

1. Nice face lift of the icons:
   
2. Frequency engineering units in graphs:
   

How long I was looking for the engineering frequency units.

It really improves the readability a lot!

 

Thank you very much, “QucsStudio”!

Daniel.

I have a question about some older bugs and limitations, were they fized or not?

1. It was not possible using complex power source impedance. Even when defined with “i”, only its real part was treated. Can we use complex sources(loads) now? It is essential when modelling real devices, like antenna frontends. (have you ever seen an antenna with wideband purely real impedance? I guess, only in 1st course textbook)

2. Since it is often essential matching to real measured load/source, there was a feature in [S-parameters] block, called “ComplexZ”. Ideally, it should have converted the simulated fixed-Z port into the measured frequency dependent complex impedance port reprezentation, with the VNA-acquired data.

But it was not working. I mean, people, including developers believed it worked, but it was producing garbage data. I checked it with Agilent-ADS, and real life components many times. In V.4 it was crippled.

Was it fixed in V.5?
