Branch: Ariane-v0.7 - Bitstream Generation Failed #165

Open Sayeed42 opened 4 years ago

Sayeed42 commented 4 years ago

Hi,

I was going with all the instructions from the documentation here: https://www.cl.cam.ac.uk/~jrrk2/docs/docs/, but the bitstream generation failed with the error from the screenshot. image It seems strange that it is not finding vivado command even after sourcing the settings script. Also, just after this, if I execute vivado from the terminal, it starts as usual. I would really appreciate some help here.

Hi Sayeeed, If you want to try a version of Vivado other than the one recommended in the docs, just modify fpga/Makefile to adjust the variables XILINX_VER and XILINX_ROOT. In this case it looks like a XILINX_ROOT=/opt/pkg/Xilinx would be appropriate. I have not tried version 2019.1 at all, you could have issues. Meanwhile I need to make sure the docs mention how to set the path. Thank you for being the first beta tester!
