Logisim-evolution library model for CMOS CD4029 counter.
Import this in Logisim-evolution: Project -> Load Library -> Logisim-evolution Library.
You should see a CD4029 folder appear in your toolbar and you can use the packaged model as a component in your design.
This aims to be an accurate model of the CD4029, implemented as depicted in the CD4029 Types datasheet from TI. While this has been accurate in my usage and test cases (student projects in Digital Logic Design), that has been at relatively low-speed operation and so I would appreciate any feedback on how this model does at higher speeds and in general.
