Hi,

I am new to FPGA and generally a novice, but I have some electronics background :-)

Is it technically possible to get OR1200 into the XuLA2 board that has an Xilinx
Spartan 6 LX25?

The board has 32MB of RAM and a SDCard slot.

Thanks, Lothar

Hi Lothar,

I haven't used an LX25, but I know that or1200 with an UART fits into an LX9. (The ethernet mac however didn't fit. Might do with some optimizations)

We also use LX45 on several boards and they generally have no problems fitting a complete OpenRISC based SoC, so I think you should be ok.

Good luck, and let us know if there are any problems.

Ok, yesterday I was unable to quote - maybe I was not logged in :-(

I tried to download the following git repo as zip: https://github.com/openrisc/orpsoc-cores
After creating my empty ISE project I added the main module as of orpsoc_top.v from
https://github.com/openrisc/orpsoc-cores/tree/master/systems/generic/rtl/verilog

Doing a validate or build main module or the like, I got errors of unknown clkgen (clkgen0).
After figuring out that I have to add all related files into the project I was a bit disappointed.

I tried to add as much as I can find, but I failed.

Is there any help to get up and running a ISE project, say in C:\FPGAProjects\XuLA2\OR1200?

I think I have to start with the generic system to create a XuLA2 system.

Is it wise to copy it from the de0-nano, as there seems to be these missing bits binding the
core to the board and then renaming all according to the bcf?

Or better, I like to create a fork and put my trials there into a XuLA2 system folger.

For what are the core and system files? I see there are descriptions what files are needed,
but what tool is used and how are the steps to get at least a HDL verification?

Thanks,

Lothar
