Threads yes, the HDL simulations will take some time
I created a new file for user settings, called user_settings.py, to control the look of the UI (font size, line widths etc.). The changes are in a new branch called "user_settings". This should also fix the hover effects you are seeing - my bad, there was a css hover definition which I played around with and forgot about as it had no effect on my system. The new approach should allow easier customization as it bundles all definitions in one place (not finished yet). I don't quite understand yet how Qt handles font size units - it seems only px works properly. Relative sizing would be better.
I created PR #9 distinguishing static and dynamic global settings. I'm afraid the PR has become relatively large as I also fiddled with variable names and the structure of the global dictionaries. The two color schemes are just an intermediate step to achieve a more consistent look across OSs.
@cfelton: could you try whether you can merge the PR (just to check whether you've got the rights)?

i.e. two myhdl related issues

... bumpy ride on the train ... channel on anaconda for even easier installation. After upgrading one environment to pyqt5 my whole Anaconda installation stopped working, so now everything is PyQt5 on my laptop as well. Downgrading doesn't work.
(sorry) HDL widget pyQt5 compatible (at least I hope so, I can't test as I don't have myhdl installed in my current Anaconda installation).
@cfelton : if you feel you would like to tackle one of the issues above, I can help you with integration into pyfda. For the time being, I would start with separate windows for simulation plots although I have some ideas for displaying myhdl simulation data in the pyfda plotting widgets.
I will test it out, in the next day or two
This chat is really a pain on my cell phone :worried: / another variable.
Pyfda can also be installed via conda now, the channel is chipmuenk/pyfda
... still working on the details:, although it says "Linux" and "py3.5"
I'd really like to tackle that for the next major release (@cfelton)
Wow! pyfda goes up into the air :-) If you need fixpoint functionality and C support, it might be worth looking into the web based tool www.micromodeler.com as well (don't know about commercial licensing though).
@sp1nelson is currently developing a zero-phase IIR filter (a bit similar to the filtfilt procedure if I understand correctly), requiring new routines for calculation impulse and frequency response etc.
As the same problem is coming up when using fixpoint arithmetics or (maybe) complex valued filters I think this is a good point for a more general discussion:
What are your ideas for extending the code functionality without producing too much clutter? I'm not a software architect, so my ideas may not be very pythonistic or expandable:

What are your ideas for extending the code functionality without producing too much clutter? I'm not a software architect, so my ideas may not be very pythonistic or expandable:
- Define a library with general design routines (impz, freqz, ...) which default to the scipy functions if possible and "detour" to new implementations depending on data types (float, complex, fixpoint) and / or parameter ranges (causal / non-causal poles/zeros) or keyword params ("myhdl", "sos", ...)
- The actual filter design class contains has methods for calculating the various reponses and formats. These could be imports from scipy or a common library or they could also be contained entirely in the class.
with the
myhdl.fixbv this should be fairly straight forward, currently we have a gsoc student working on the fixbv features and the backend compiler
we can currently use the
fixbv for the fixed-point analysis and coefficient generations but it will be quite a while before we can use it directly in the filter HDL implementations.
