DIP40 - Soft Propeller module, runs Parallax Propeller IP in FPGA + 2 Cortex A9
This project was
created on 07/15/2015
and last updated 2 days ago.
Note: propeller verilog was released under GPL, later there was offical statement on Parallax forums that commercial use is also acceptable without need to stick to GPL. This should be verified however. It seems some old forum threads have vanished. In any case once release under GPL can be used under GPL as this can not be revoked. And the use of Propeller code is not all required, it is just on possible use case.
Is actually ready in the factory, I did see it today. SMD assembly is done, Through hole (the pins!) assembly is be in progress.
all hardware CAD sources and generated files on Github main repo

Hello, Actually i am working on a project using Zynq7000 Socs, but i need more IOs in my design. How many IOs is it possible to add to your project?
in dip socket are 34 io, if you count all connectors then 42 io + 3 more input only pins are available
Excuse me, you mean that I can use 45 more IOS and this board countains already 34 IO ?
no, sorry: in the DIP40 header: 34, in the other headers: 4 + 6 + 2 + 3 input only, so abs total max use: 42 + 3
In my project i will be using about 80 IOS, is it possible to redesign the PCB and extract more IOS for example or what do you advice me to do.
and excuse me for this question what is the designation of the NAND Flash, because the documentation doesn't indicate.
16mmyte quad spi serial nor flash, can be accesses as XiP linear memory also, no nand
Thnks for the informations, but what is its reference in the Design that you putt in GitHub ?
Nothing yet, but for sure there would be propeller demo, and some logic analyzer, and maybe something else to get started.
I am on vacation actually, so my time is clustered and limited atm.. hence the random replies
Clg225 has total 54 fpga io and some on the processing system so with package 80 io is not directly possible. But if your system includes slow and fast peripherals you may add io by using say simple serial registers fpga can scan them very fast
Are you going to be posting the design files? I would be curious to see the schematic and layout documents. Which tool did you use to do the board layout?
By the way, if you release the CAD for OZoM before this you round my day.

ozom-a CAD files are actually released, they are on public access SVN server, with not so widely known url.. i try to change this, probably by duplicating the sources to github or somewhere else

Can you post the URL on indegogo page? We're waiting like KIDs on christmas.
this are the original sources for the first batch manufactured, I push the info to other places too
see project log, I compiled prop v1 code for 7010 its about 50% of LUTs. Xilinx does not count LE as Altera. Bit more than 50% of LUTs are used from other resources less than half.
BGA is simple both for manual as for automatic assembly. As long as you do not go below 0.8mm pitch, you can use pretty much any PCB fab. The fab we use for small batches does have production panel size of 360x460mm, and no discount on repeated order, and prices go up if you order more boards. You pretty much pay for the full 360x460mm always, or it does never make sense to order less than 1 full panel (this could be your multiproject pcb with 50 projects..). The price of one panel is from 300 to 1000 eur. I do not recall what the DIP40 boards did cost, it is OK for first runs, for larger volume we need to use other fab. For small runs:
Hi, cool project! Can you comment on what PCB factory you used and how much that one panel cost? I have done some Spartan 3 and Spartan 6 projects with TQFP-package and 2 layer PCB. But all good stuff seems to be packed on BGA:s now days, so I am very curious how to get there.
We produced 1 pane = 4 PCBs, we had 5 pieces of ZYNQ for $$$ money, we have ordered from "quote pricing" - but this takes some time to arrive. But we do our best not to delay. We have some PCBs from first batch, stencil is there. So we do more testing, and then its up to Avnet when they deliver the Zynq.
it is 6 Layer PCB, yes I will post more pics, the board just was produced yesterday so I had no time to make real photos, just with my handy some quick shots..
This is a great product that I wish to have couple of them, can you please post the back side pictures?
