Improvement: Verilog files do not have a library

[patrick-studer]

When using the IpPackager with Verilog files, Vivado shows the following warning:

I guess this can be removed by not defining the "set_property library" if the fileType is VERILOG.

Addidionaly, the filetype could be derived from the fileextension (.vhd, .v, .sv)

We currently have no experience with adding own verilog files to the package. If its still a matter, I will implement the different handling depending on the filetype.

Because it is not a bug but an improvement, I guess it can wait... I just placed it here because Vivado throws a bunch of warnings and to get rid of unnecessary warnings is always good :)

I will find time in the next few weeks to implement this improvement and test it with the project that uses Verilog files.
