First I would like to say that chip is working. Complete confirmation using test-vectors.

https://mega.co.nz/#!yVMTTCSA!SFsVTAWeMSnxwUeuRnwR0Wm_d74xVyOdxkL5LEI_LsQ

Here is SPI code to download and test code.

Then - measurements of error rates and real hash rates were performed using 100 first test vectors (as enabled in code), no board cooling (that's pretty impressive - it works on PASSIVE board made by Rene - great thanks BTW - you may use code I provided to perform same tests... Maybe just oscillator should be adjusted - on OUTCLK you'll see clock and you should bring INCLK and OUTMISO to ground while testing).

Results so far

0.596 V, 125 Mhz, 100 tasks sent, 122 solutions got, COP is 0.84 (122/145), Ideal 1.45 GH/s, Real 1.22 Gh/s
0.596 V, 150 Mhz, 100 tasks sent, 19 solutions got, COP is 0.13 (19/145), Ideal 1.74 Gh/s, Real 0.23 Gh/s
0.596 V, 78 Mhz, 0.6 Amps, 0.36 W, 100 tasks sent, 145 solutions got, COP is 1.0, Ideal 0.91 GH/s, Real 0.91 GH/s, 0.39 W/Gh/s
0.596 V, 45 Mhz, 0.39 Amps, 0.23 W, 100 tasks sent, 145 solutions got, COP is 1.0, Ideal 0.52 Gh/s, Real 0.52 Gh/s, 0.44 W / Gh/s
0.596 V, 96 Mhz, 0.725 Amps, 0.43 W, 100 tasks sent, 143 solutions got, COP is 0.986, Ideal 1.12 Gh/s, Real 1.1 Gh/s, 0.39 W / Gh/s

Please note that it seems that 96 Mhz is close to _BEST_ solution... Then I started to increase voltage, while not changing internal oscillator settings - it is not power-stabiized and its oscillation frequency
should follow and grow up. What is most interesting (and this should be confirmed later - this is INTENDED operation) - that oscillating frequency increases, while error rate remains the same as transistor strength in oscillator and interconnect variances within same die are less.

0.7 V 140 Mhz 1.2 Amps 0.84 W 100 tasks, 143 solutions got, COP is 0.986, Ideal 1.63 Gh/s, Real 1.6 Gh/s, 0.52 W / GH/s
0.8 V 180 Mhz 1.87 Amps 1.49 W 100 tasks, 139 solutions got, COP is 0.958, Ideal 2.093 Gh/s, Real 2 Gh/s, 0.75 W / GH/s
0.9 V 214 Mhz 2.62 Amps 2.36 W 100 tasks, 132 solutions got, COP is 0.91, Ideal 2.48 Gh/s, Real 2.26 Gh/s, 1.04 W / Gh/s.

Not tested more... And likely latter was worse due to not enough cooling.

We do not need more just confirmation testing that it works, but we need more extended testing like that. So I'll discuss tomorrow with Leszek and we'll send test chips, and will ask to perform tests and post your results. Also we likely will make some contest for say - best USB-stick (most of hashing power with smallest form-factor), highest hashing rate (real, not ideal, crunching clocks is not a problem), etc.

I would like to note that THIS design thanks to much effort spent in Monte-Carlo sims with flip-flops works really well at low voltages :-) Small error rates and no flip-flop losses like it may happen with logic cells unqualified for low voltages. It scales almost like it should in theory, not like it does in practice when cells are unsuitable and you simply can't go lower because frequency will drop DRAMATICALLY. This enables application of this chip for different kind of heating devices where voltage can be changed in dynamics to adjust produced heat to requirements, etc etc etc.

Also I am preparing to execute payments to all betters, because it is clearly our fault that we failed to meet deadlines. It is too cumbersome to calculate actual bet amount, so I would pay off using averaged multiplication value about 1.86 or so (I don't remember exactly have to look in my calculations).

Thanks that we ordered more wafer count - we now can fulfill say 100 Th/s operations, etc :-) So there's nothing to worry. And we can start planning for further testing and production.

Congratulations then!

As far as further testing you should measure hashing rate of the chip when immersion-cooled in champagne. At the same time you could test your own hashing rate while ingesting champagne.

I don't know you from Adam, but I must say I am impressed.

It seems integrity is in short supply in this forum, but you appear to have a surplus.

Godspeed good sir.

+1 impressive
 
It is too bad you don't sell your products to the rest of the world though... you allow lucky Russian citizens to charge huge mark ups for customers wanting to buy your product in the rest of the world. If they are going to ship worldwide for a profit, why not charge more and ship worldwide yourselves?

I would have bought some units, but honestly I didn't want to order through some sketchy Jr. member. I trust you Bitfury, but not some random person that is reselling your units for profit...

Does "100 Th/s operations, etc" include Metabank too?

Congratulations! I now look forward to the next announcement with you guys selling your chips in bulk so local builders can manufacture goods based around your design. Truly impressive results that bode well for some energy efficient builds.

I've been wracking my brain all night, trying to figure out why I was getting sent 0.1btc from bitbet, then was linked to this thread from the bitcoin subreddit, relating to the testing being done. I have to say I'm impressed with the current results, and have high hopes for this project to continue to develop.

Bitfury, you are among the very rare honest ASIC sellers with great integrity. Hats off to you, comrade Smiley
If I could, I would invest the amount from the bet in even more of your miners.

You were right bitfury, the initial input level shifter circuit
was not working correctly. Seems the the parasitic capacitance
of the 1V8 zener together with the 1K input resistance caused
severe detoriation of the waveform due to the RC-delay.

Redid the circuit: increased the current by lowering the
resistance to ground and replaced the zener with a 3V3
type connected directly to in the inputs. Did also some
measurements, looked not that bad. Inputs SPI signals are
divided to 1V8, output SPI signal is level shifted to 3V3.
See image:



This is still with a bare board, no ASIC yet. Might need
to lower the restistors even further to get crisp edges.

Will first look into the SPI code now.

Can someone translate what bitfury said in his long post? As i understood there are more measurements to be done, but the chip is working, but it isn't good enough for a big rig? I can't wait for USB miners with this chip.

Also i'm impressed too for paying for that bet! Now just give me the change to be your customer bitfury! Cheesy
