Hi, can the Bter.com admin please come back to me . We need to settle some very urgent matters.  Thanks

Try Tomatocage as escrow. He's a mod on here. https://bitcointalksearch.org/user/tomatocage-37522

What happens, did he disappear without a trace after failing to convinced everyone on the RTL, VDHL and support for analog part, PLL?

Hardly any news from him. I told you so it is nothing but "      "

Hi Freeworm,
I don’t know if you are from btc-garden. I am quite interested in this opensource idea, I fully support a opensourced mining asic.
However, I think the best way to make it work is to do it for free.
Personally I think 200 bitcoins for an FPGA code is too expensive, since you can easily get it from openFPGAminer project where it is free and opensourced. What’s your improvement?
That doesn’t mean I don’t what to contribute on this.
As I am also a chip designer myself, I am more interested in the technical level details. There are several question marks in my mind.
1.   As I know, it is a long way to go from FPGA verification to an asic chip. Unless you don’t care about the performance. FPGA has its own architecture, and optimized for flexibility.
2.   According to my experience, to get 300MHps is not easy. As you don’t have the final physical design ready yet, how did you estimate a performance of 300MHps in the 110nm technology? Only using FPGA tools like Quatus is not possible at all. Which EDA tools did you use to estimate the performance?
3.   The SHA256 core is complex and contains tens of thousands of logic cells. For one or two designers, manually routing the design would be as hard as going the moon by foot. Typically the layout is done with EDA tools automatically. You mentioned 20-30days of work for the layout, and does this mean fully manual layout, or using EDA tools for the routing? I heard that Intel designed their early CPUs fully manual and I believe it since they have many personal months. But BFL claimed their chip “100% Hand routed for performance density” and I doubt about it. I totally agree if it is only for the packaging
4.   There are many technique details for an efficient asic SHA256 core. E.g. In a FPGA implementation the PLL is only used for generating the clock. But in an asic the clock can be used with multiphase, which can’t be simulated in FPGA.
5.   You mentioned the most difficult part is prototyping in FPGA, but I think the most difficult part is to optimize the design. That includes optimization of the algorithm, the layout of the chip etc. It seems you haven’t provided any technical details about it now. Getting 100MHps in FPGA is not difficult at all. If you provide slack information in your asic design that would convince more people.
I guess the initial purpose of the project is to profit, now making it opensource means no profit. But asking for 200BTC is still charging something. What is your vision behind this?
Anyway I fully support the opensource idea, and I hope more and more discussions going on with this topic. I am glad to get involved into making an opensourced asic miner.

you guys think there's only Place & Route work between fpga verilog and ASIC design? what about analog part, PLL?

Hi

what i need is an rtl of vhdl to be able to study and progress on this

ztex have provided his own and has being used by avalon as well as bitfury as a base for their design

so make it public and we can see if we can work it out


thanks

The FPGA firmwares included in the main post are generated from our VHDL/Verilog source codes.
We tested them on three De2 boards hashing at around 100Mh/s as show below


Since it does 1 hash per clock, on a 110nm asic chip running at 300MHz, it will do 300mh/s, the same as Avalon's chip does.
A 40nm chip can run at 800-1000MHz, so it will do 800Mh/s-1Gh/s.

Muti-core chip is also possible.

do you have a vhdl or rtl for this?

on fpga should this work?on wich one did you test it?what speed of hashing did you get?

thanks

Hi,

We have provided our FPGA firmware of your ASIC prototyping and the main controller in the main post. Anyone can test it. It's real.

Suggest you put Eve on ignore... and let him wear his tinfoil hat on his own.

Instead of throwing around accusations eve why don't you show some proof for the first time in you life?

the writings are on the wall, is a scam

interested

at wich stage are u at the moment?

This would be an interesting project if the community could keep it open source and any contributions to the design would be open sourced and not kept proprietary.

Basically, it would lead to a open source ASIC chip that anyone could contract to have manufactured ... would really make bitcoin distributed ...

Who would want to escrow a scam, no one will. xcrowd was another one.

John K. haven't given any response until now. We need to find a new well known escrow. If somebody knows, please advice.

From our experience, the most difficult part of starting a bitcoin mining ASIC chip is the prototyping design on FPGA.
One team needs at least one FPGA expert, one ASIC expert and one Bitcoin mining algorithm expert to finish it.
It usually takes 2 to 6 months. Avalon, BTCGuarden, and labcoin are all the examples.

labcoin collected 7,000 BTC from its IPO when they just finished the FPGA prototyping for the 150nm chip.
BTCGuarden collected ~10,000 BTC from its IPO when they claimed they were going to tape-out their chip.

We also collected 3,000 BTC from MYMINER IPO while we even didn't mention we had the ASIC prototyping almost done.

Since we have already finished this ASIC prototyping part, it will save people a lot time who want to tape-out the real chip.

Anyone who gets the source codes of our ASIC prototyping can generate a netlist file and send this file to an IC design company or person for IC layout design.

Layout usually takes 15-30 days. Once it's finished, one can send the layout to the fab for tape-out.

Usually the IC company can do the layout and arrange the tape-out for you together as a package service as long as you can provide the netlist file and pay them.
The only thing you need to worry about is the ASIC prototyping while we have already done it for you.

   No worries man,we all snap from time to time   

I ignore no one,I just consider the source & move on 

If your a scammer,it will show soon enough (look at pirateat40,he is soooo screwed now that BTC is "currency"  ),if your not,it too will show 

Back on topic: I'll be watching & waiting for results to prove that this is legit & works & is affordable.

All these ASIC guys want big money,not much for us poor folk to chose from......................

This is what i also don't understand. However i don't understand nothing about designing an asic chip, so i must be wrong.
Trusted escrow, that will do it for free? I don't know any of it.

Sorry Unacceptable. You're right. Must be time for a snickers bar I suppose.

Guess I'll just need to use my first ignore.

Sorry for the thread hijack freeworm. Don't mind my thread outburst. I've put a lot of time/effort into starting my services & to have someone call me a scammer without a single shred of proof when I've been completely aboveboard with my dealings with people's IDs, cash, and BTC & have gone out of my way to help newbies and forum members, just rankles me after the day I had. Like I mentioned: the actual escrow depository services & 3rd party dispute resolution is handled by BTCrow. I'm an official BTCrow Escrow *Affiliate* and not an Agent. The offer still stands.
 
I can also mention dabs as an escrow service that's avail. He runs an actual MSB service in the PI. SebastianJu is also a standup guy.
