I got my FPGA installed. I don't like that it doesn't come with a metal bracket to keep the board from touching my videocard. I'm kind of afraid to leave it in my computer for any long length of time. My throughput using the Thruput Demo is 640 MB/s read, 461 MB/s write. Is that similar for you? Lastly, to get your Diamond license, log into your Lattice account and then go to support->licenses and you can request it. -----sig: |

I have a daunting feeling like I'm going to to feel in-over-my-head for the next few weeks at least. Thomas Fjellstrom said: Haven't had a chance to test it. Just download the test from the website, and run it. The bitstream is already on the FPGA. The windows driver for it is located in the zip file as well. Also, Lattice Diamond default directory for searching for the license file is NOT C:\lscc\diamond\2.1_x64\licenses\ even though it said it was. The environment variable wasn't set like it should be, and the default is C:\flexlm\license.dat so I just made the directory. -----sig: |

What the crap? Send it back and deny the charge. I bought mine through a vendor, not their website. But I live in the US so I don't know what import will be. As for the licensing, I think that's pretty common (you pay per "seat" per year) and I've heard that they're pretty good about sending you a new key if you change platforms. You are potentially playing around with tens of thousands of dollars worth of software IP cores. On a related sidenote, I've been playing around a lot with Logisim lately, a free digital logic simulator/designer. It supports subcircuits which is really cool and useful, so you can design an ALU and then back out and use a single ALU control block. -----sig: |

I talked to them about it, got a bunch of the extra refunded. Not all of it, but w/e. -- |

In our first semester of uni, we had to make a simple 16-bit processor in it and run some simple programs on that using a simple assembly language. " There are plenty of wonderful ideas in The Bible, but God isn't one of them." - Derezo |

In our typical public college we probably wouldn't do stuff like that till our last year. Although, I was recently watching some lectures from MIT/Stanford/etc and telling my wife how the pacing of their classes (two to three CS topics per class meeting and zero hand holding) is way more my intelligence level (whereas I'm bored to hell at my public institution's slow pacing). So once I get a job, if I go back to grad I'm definitely going to consider going to a higher up university. -----sig: |

I've done VHDL on altera and xilinix. I also bought a $11k pci-e fpga on ebay for $300 from some Israeli students who were done with it for their project. [EDIT] it's an altera stratix card. (\ /) |

doing research all day today, and going to see the new Star Trek movie tonight (leaving right now actually).
When did you get married and where was my invite? 
I've been dealing with the whole "my spine is collapsing" thing and subsequent transformation into wolverine over the last two years and she's been there by my side the whole way. She's my other half.
