I have two students in my computer architecture class that are attempting to run  the rvFPGASOC project and have run into some errors. They followed the directions in the lab1 file exactly, and when they attempt to build the bitstream they get the errors. They are using Vivado 2022.1 executing on windows. I observed them attempting the install via a zoom session, and i believe they followed the documentation exactly.



I am including the snapshots they sent me and a message from vivado:

[filemgmt 56-585] Internal Data Exception: HDDASrcFileProxy::HDDASrcFileProxy: Given Source File 'C:/computerArchitecture/RVfpgaSoC/Labs/LabResources/Lab1/src/SweRVolfSoC/SweRVEh1CoreComplex/include/global.h' needs to be addded to the project in order to use it as an RTL module

Please let me know if you have seen these error before.

Hi Nick,


Thank you for reaching out.


I notice you are trying to run RVfpga SoC on Vivado 2022.1
RVfpga SoC is designed for Vivado 2019.2


Whenever Vivado does significant upgrades, there are always subtleties and steps that don't work that well.

We recommend trying Vivado 2019.2 and see how that goes
That should work ok.

Let me know if you still face issues.

@zubairlk I recommended to my students that they try 2019.2. They also tried lab 3 which used fusesoc. They ran into the following weird error:

One of their classmates was able to use a newer version of vivado with fusesoc to complete the linux lab. Any ideas about the error?

Found a subtle issue which we'll fix.


Can you please either temporarily downgrade FuseSoC to version 2.0 with "pip install --upgrade fusesoc==2.0"

or remove the problematic line (this one P">  ).

It is not used in this context and can therefore be safely removed.

@ndbeser I have confrimed this is an issue with FuseSoC 2.2. I just released FuseSoC 2.2.1 to fix this issue. Please upgrade with "pip install -U fusesoc". Hope this helps
