I have noticed that there are a serious lack of HDL (hardware description language) tools on the internet in free/open-source form. (stuff such as Verilog and VHDL development platforms).
I've used Active-HDL in school before, and it is an amazing development environment, but it also costs a lot of money. Considering the fact that I just like to play around a bit, and I don't actually want to design hardware in a hardcore way, it is not feasible to buy such a product. There are also some other tools that I have seen that cost a ton. In terms of open source software, I have found very little. I find little things here and there, but nothing fully developed and awesome such as the things we have for C++ development (like Code::Blocks for example).
Does anyone know of any freely available HDL tools out there that are mature in their development cycle and work well?
So far I have the following:
GPL Cver 2.12a
Wave VCD Viewer
Cver is not very well documented at all and so I would like to find something else if possible.
