Hi all,

I am trying to synthesize a standalone fusesoc project (using quartus prime pro) to simulate mor1kx_cpu module for some specific conditions using modelsim. Other than mork1x_cpu module, I would like to add the wb_intercon, etc. modules to be able to add a memory and peripherals.

When I followed the tutorial here "https://github.com/olofk/fusesoc", I was able to create the fusesoc directory and initialize the fusesoc tool-set. However when I try to fetch a core, I get the following error message. I should mention, I used cygwin to install fusesoc and when I try to untar any other file, it seems working but somehow whatever the fusesoc is downloading cannot be extracted successfully.

any idea why this is happening and how can I solve it?

Thank you.


$ fusesoc fetch mor1kx

Fixed.

It turns out the problem is about Python version and the libraries that are used for downloading web content.
