Lately, in our university we’ve been tinkering with the simple 8 bit processor PicoBlaze, for which there is a little simulator out there called “PicoBlaze IDE”.
But as it seems, there are no OS X versions available. So, like before, here is a small port (thanks to Wine) for Mac OS X. I have tested it on three independent Apple machines, running OS X 10.10 and 10.9 and it worked on both.
You can download the Mac version here: pBlazIDE.zip (250.6 MB)
Alternate version: if you have any problems with the version above try using this one: pBlazIDEv03.zip (295.4 MB)
As to why it takes so much space: the app bundle contains all the necessary wine support files, in order to run the app without having to install wine into the target computer. Also, should you have any problems running it, it seems like in some cases having X11 installed in your mac allows it to run although it is not always necessary.
