I want know where I can find theoriginal altera wiki website，the https://fpgawiki.intel.com/ is gone!

Sorry, this simply doesn't work. It redirects to a general intel community page which is nothing like the altera wiki. The altera wiki was a very useful site that had hundreds of files stored on it that your customers used to help develop products on Altera FPGAs. Please restore it. You can change the name to intelfpgawiki if you want, but the same content and format needs to remain. Redirecting to a general intel community page is useless, you might have just as well announced that you are killing the altera wiki. You apparently have no understanding of your customer's needs or how to support the fpga development community. This is an abomination.
