This program generates an image of your quartus .bdf or .bds files. I've only tested it with Quartus 9.1 so I'm not sure how it will work with newer/older versions,
but the way the functions are implemented it shouldn't crash too badly. I've tested it in the newest versions of Firefox and Chrome, also as an added bonus it seems to work fine
on iPhones.
To see how it is supposed to work try running it with this sample file http://bdf.arcwb.com/sample.bdf
Disclaimer: I don't save any circuit files you upload. The only reason you have to upload them at all is because a key security feature in JavaScript is that you can't
open files on a remote computer. Also uploading the files means they can be processed with PHP which is admittedly a lot easier to work with than JavaScript.
