FPGA Replay Board
 
Hello to Mike J and Yaqube.

I know you guys are probably swamped in work and out shopping mega-pacs of fireworks already, but could you see if you could publish images or youtube clips of the Replay board itself and when operating and maybe also with the 060 daughterboard installed ?

We would be glued to the monitors, even at 23:59:59 at 31.12.2010 if you do this....screw the fireworks :-D


Merry X-Mas and a hapyp new year!!!

Frankly speaking there is not much to show right now. Everything has been delayed slightly.

I should get the new revision of the board shortly after Mike has verified the design. The daughter board should be ready in January.

In the meantime Tobias has managed to implement missing bitfield instructions. It has increased the core size to 75% of the FPGA.

We are still working on fixing minor problems. Finally we've got the RNC Copy Lock games to work.

Cheers for the info. Sounds like things are just about done with th exception of a few morer tweaks.

Just out of interest, will/can the AGA core be ported to the C-One?

What will be present on the upcoming daughter board?

The current Minimig AGA core needs circa 25K logic cells. The Cyclone-III on the C-One extender has 24.6K LCs but some more are required for another CPU core acting as ARM MCU replacement.
Actually it's very hard to use more than 95% of the FPGA due to limited routing resources. It's hard to tell for sure but with clever coding it might be possible.

I will post more info when I have the board on my desk running.

@ Yacube
Count me in for a daughterboard ;-)

@yaqube, 75% of the Spartan-3E 1200 ..?

75% is a lot, and makes me wonder about the space for the AGA core etc..

75% of the Spartan-3E 1600

75% is taken by: Minimig AGA core (with 24-bit scandoubler) + SDRAM DDR memory controller + TG68.C (V0.40) + dual CPU caches + 16-bit DMA AHI sound card module + 128 channel embeded logic analyzer

Re: FPGA Replay Board
 
I am waiting for the replacement LDOs to arrive to verify the problem with power off has been fixed. They got delayed by the Christmas holidays, but I should have them Monday. I'll then ship the board to Yacube.

I have been working to improve timing and area in the design so the compile time is reduced.

Trust me, we are not hanging around here...

Isn't the fpgaarcade equipped with an Spartan-3E 1200 ..?

That sounds better ;)

Re: FPGA Replay Board
 
From what I recall, the 1200 got replaced with a 1600... It's somewhere in the very long thread.

All I know is I want Both (money already set aside), also want Natami then i am one very happy boy... (except i would have to wait for AROS 68K)

Is the Picasso96 driver getting some love? ;)

Yes but right now the priority is the chipset and CPU compatibility.

This is great news Mike and Yaqube. We love your dedication and the fact that you spend so much time on this project. I do hope your will make some money on this awell.

Re: FPGA Replay Board
 
How much does the pcb board itself without any components cost?
(size?, layers?)

mikej 01-01-2011 07:18 AM

Re: FPGA Replay Board
 
It's 6 layers and you can get the size from the drawing on the website.

I'm not prepared to discuss component pricing as the board is not available (and no use) on it's own - you can't self assemble this.

It's pretty tough to hit the price point I am offering it for in these volumes. When the manufacture moves completely to China it will be a little less.

Re: FPGA Replay Board
 
Just curious what pcb price you got for small runs for use in other non-amiga related projects ;)

mikej 01-01-2011 09:43 AM

Re: FPGA Replay Board
 
Sure,
The PCB company I use is called Shenzhen Gold Sky
http://www.gsspcb.com/en/

My contact is called Lily, who is great.
The price depends a lot on volume and the design, so send them the manufacturing data and get a quote. The NRE is quite high so you need to be looking at 50+ to make the overall price good, then it gets quite cheap.
Best,
Mike

freqmax 01-01-2011 09:36 PM

Re: FPGA Replay Board
 
I think a small run = 4 cards, I thought you used another one more physically close. ;)

As I recall you used one company for the first 10 (or one?), and another one for the full 50?
