Vivado Synth. error: integer value too large

[Butterkeks]

At the moment I'm trying to get the Digilant CMOD A7 GPIO DEMO (here) up and running on my cmodA7-35T.
Till now I'm working throw the Digilant Tutorioal how to use the DEMO Projects (here) and have a big issue at 3.1 Generate Bitstream.
If I'm trying this, I get the error message "...

integer value too large to represent
ERROR: [Ipptcl 7-5] XIT evaluation error: integer value too large to represent
ERROR: [Common 17-39] 'xit::source_ipfile' failed due to earlier errors.

"

Does someon have any Idear how to solve this?

My System is:
Linux Mint 19 with Kernel 4.15
Vivado v2019.2.1 (64bit)
 

Thank you very much for any help!

Hi,

the download page says

Vivado 2016.4 is used in this tutorial

but you're trying 2019. Porting a project to a newer Vivado version is usually not trivial. The easiest way ahead for you might be to simply install the correct version (I know it's annoying but I wouldn't try my hands on a conversion unless I'm a fairly advanced Vivado user. For Digilent it is quite obviously not feasible to provide and maintain every tutorial for every version, there are usually three or four a year)

If I would set up a project from scratch (which isn't that hard, the only file I'd import is the constraints file), I'd use the latest available version

Hi xc6lx45,

thank you very much for your fairly true answer!

Since I only want to have a example for the USB-UART bridge, I now also found a old basic github repro which seams to work quite well for my purpose.
So I will try to avoid the annoying roll back to Vivado 2016!

So Thank you again and happy Projecting
