I've got a new toy on my desk. It's on loan, but it's a Virtex-7 2000T. This baby would take a full Amiga Chipset + CPU (many times over) and early runs with Synplify + ISE have MiniMig 68k meeting timing easily constrained at 100MHz

Shame it cost over $100k :)


I have now one of these on my desk. Somewhat less powerful but also less costly :).
Also don't have the commercial software with it, so I am interested to see what IP I will be missing.
Unfortunately did not find a time to start it up yet.

PowerPC on FPGA within grasp then finally? ;)

@Fats, tried raw S-ATA with the board ..?

Very nice Alex. We were trying to get one of those for prototyping, but we brought the largest Virtex-6 we could get instead. Still pretty big :)
Enjoy... what's compile time like when you get it full? I had to move to a 64 bit Linux box for both Synplify + ISE with 32G of RAM!!

LX720's are so last year ;)

Something in the realm of 8hrs on our fastest Sandy Bridge Xeon. But it doesn't help that it is partitioned over the two FPGA's in the 2000 using Certify's auto partition. This is all on loan and using minimal constraints.

Our real stuff on LX330 + FX550T is much faster due to manual partitioning at the design level and strict constraints..

@mikej, How many Hz and CPU type for that box?

Guess for larger FPGA:s compartemilisation is the feature. Lest synthesisation is going to take lots of time..

Synthesis is very quick, 10's of minutes. MAP & Optimize + Place & Route takes the biggest amount of that time.

That's slow for the developtment loop. Edit-compile-test-repeat..
But the time from HDL to binary needs CPU and frequency to be of a comparative nature.

No. Unfortunately the only thing I currently did with the board is look at it every time I enter my room.

I am interested in getting an Arcade FPGA =) (including a backplate when available!). What is the current availability situation... and price?

Thanks!

im interested in buying the fpga arcade and atx adapter, when the fpga arcade expansion is available too for the 68060 cpu.

About availability, will FPGA Replay ever be sold through Amiga Kit or other retailers?

Did a bit of playing with the device.
IOs on the Spartan-6 chip only go to 1.06 Gb/s; SATA1 needs 1.5Gb/s already. Will see if I can use USB stick for storage.

@Fats, see if it will work anyway? perhaps it works inoffcially ;)

Guess it lacks "rocketport" and interleaving hack won't work?

Hi, I've arrived back from China and board testing continues...

Out of curiosity how do you test the boards?

I have a test rig and a special FPGA build - thats the advantage of having an FPGA :)
