VIM : syntax highlighting gone after clicking another file

I have a problem with syntax highlighting in gvim. i have the following command in my vimrc file:

autocmd BufNewFile,BufRead *.v,*.vs,*.va set syntax=verilog

However if i'm in gvim reading a file - "a.txt" and i also have "b.txt" open on split, when i click on b and then return to a , the syntax highlighting is gone after the click. someone tried to explain to me that the autocmd not always running. any ideas

The BufRead option only applies when reading a file into a new buffer, so it makes sense that simply switching between splits won't trigger the auto command. The file has already been read into the buffer; it's not read again unless you close and reopen it.

You want the option BufEnter, as it triggers on entering a buffer. Your new command should then look like:

autocmd BufNewFile,BufRead,BufEnter *.v,*.vs,*.va set syntax=verilog

As a side note, it's probably better to use filetype instead of syntax, as syntax won't affect indentation rules, if there are any. Or even better, use a plugin to get everything set up automagically without needing explicit autocommands in your .vimrc. Just from a quick Google, this plugin pops up a bunch.
