This thread is full of valuable information.  Now i know exactly when to visit Sweden (and the Balkans)!

Mmm...frolicking beer-covered blonde co-eds and ASICS...

I noticed that on their linux machine, they even had a seperate console utility to monitor the status of all the FPGAs (temp, current, power usage etc), this means that they have a whole suite of FPGA related design platform, and they just fit bitcoin's hashing function into that platform

And they said they are not going to have an ASIC prototype, just replace the FPGA with standard cell ASIC and direct go for mass production. I think this is risky, without a prototype, how can they sure all the heat and power usage fall in a reasonable level? Unless they have done this many times before, they might encounter what BFL experienced last year

As the Swede I feel responsible for explaining this weird phenomena.
When Swedes graduate at third year of Gymnasium,
We celebrate that we now are unemployed and without a job by jumping on a big truck, half naked, spraying beer on each other and everything that moves while listening to loud music.
It is just a normal day in Sweden xD
//DeaDTerra

maybe graduating from the university would make it easier to get a job??
Yep Tongue
Which is why it feels a bit weird celebrating after gymnasium. I guess it is stuck from the old times when almost no one had higher education.

He did, they said something in the lines of that it is a linear progression from the FPGA.
And that you can make some basic calculations to estimate both the watt and the hashing power based on the FPGA performance (as I understood it).

Trust me, UK wise; graduating from university does not mean it's easier to get a job! Grrr...

It guarantees a lifetime of debt though!!

ORSOC have pretty damn solid background in fpga design and development as far as I understand. If they are betting that they can do a pretty straight swap from fpga -> ASIC I for one would probably bet they know what they are talking about.

fwiw Sweden has some pretty damn talented engineers and programmers, especially in open source and electro mechanics.

Yes, thanks I'm aware of that, it was free here, until the bloody year I started!! Cry

All Scandinavian countries give great education! Wink

In Norway there is practically zero reason to ever leave education, their PhDs are as well funded as the jobs people do them for...Undecided

I asked them and they said that simulation of that part is done by the chip manufacturer, they only have the simulation at rtl level

Why u dont ask them?

as i understood it they are experienced with heating/cooling problems and approaching it with being flexible in both the number of chips used per device and extend of load on each chip in an overall modular setup.

They will be air cooled. I'll evolve this later on.

As I remember, the first set of BFL wafers (last December) just went to trash bin because it either over current or over heat, no way to make them work, then the second set wafers (this February) ran at half of the designed frequency and still draw double amount of current than simulation results, so only 2 of those chip can be powered and sit in a box that originally designed for single SC. Now they have rest of the wafer using a different metal layer implementation and further improved the power draw and heat, but still by no means reached their original claim of 1w/Gh, more like 5W/GH

But anyway knc's estimation is 3W/GH, that is quite reasonable for a 28nm chip

Air cooling: fans= $50
