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.
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.
So, a couple of years ago i set myself to find a simple program that could perform simple digital algebra operations. Eventually i found Logic Friday, which turned out to be simple to use, fast and powerful enough for simple problems. It is basically a GUI for espresso and misII and it works wonderfully. However it is only available for windows, so here is a simple Mac version of Logic Friday (thanks to Wine). I have tested it in multiple apple computers running 10.8 and it worked fine.
All the credit to Sontrak (where you can download the original windows version and obtain further information on the Logic Friday tool) and to the espresso and misII tools*
