Hi,
I have forked and moved everything to after folder, so the highlighting is loaded after the default vim's highlighting, if u wanna merge your code, you are welcome: [https://github.com/leosmaia21/vim-SystemVerilog]

However, I've already used a new configuration. My script enhances UVM highlighting and makes it more concise. Feel free to use it: https://github.com/sqlmap3/systemverilog.vim
