Re: [myhdl-list] co-simuation

[Edward V. <dev...@sb...>]

Chris,I did run this on the a Ubuntu 12.04 on an AMD processor.  I get the same results as on the Pi.  
Dave is working on Lattice ICE-40 board for the Pi and I wanted to get some tools working on the Pi.  So far I have I been able to get GTKWave, Myhdl, Iverilog, vhd2vl, FireFox, Python 2.7 & Python3, XSTOOLs(XuLA2-LX), samba and OpenCV  on the Pi.  The O/S for the Pi was created with Yocto which creates a custom Linux Distro and the supporting cross compiler.Also a tool which is needed but not running on the Pi is Yosys which is the tool used to generate the bit file for the Lattice ICE-40.  This would in turn createa standalone HDL development system at a low cost.  Dave indicates the XSTOOLs will not be needed for Lattice ICE-40.  The bit file will be downloaded using GPIO instead of the USB.  Dave tweeted last week that the board was almost ready.  I hope I stated everything correctly.

If you have any questions let me know.

You might want to try running it on a desktop system
first, that way you can isolate system/OS issues.
Quickly reviewing the code nothing jumps out.  My next
step to test it on an x86 desktop linux.

I have to admit, I am a little confused why you are
running the toolflow on the RPi2 - what is the goal?

Chris
