Create a major-mode for "log files"

Looks good.
Is this for any specific simulator - like ncsim ?
If there is a code, I can test this out.

Yes.

I haven't yet started working on this as I got something workable with the help of in-buffer Hi-Lock patterns -- Search for Examples of Hi-Lock patterns here.

That solves:

Highlight error/warning

.. which was the main reason I want a major mode.

For now, incremental search (C-s) takes care of:

Navigate to next error/warning

Actually I remembered I have already committed the .dir-local.el file for log files here. You also need to allow setting of hi-lock-file-patterns via .dir-local.el as safe.
