Is there a plugin to show the definition of a variable quickly, just like the vs code ?

For example, in vs code, when you place the cursor at a variable (e.g., when i am programing with verilog or other language), it will show the definition of this variable.
I wonder whether this feature could be enabled in emacs ? (maybe I need to install lsp ?)

I think lsp is too heavy, I wonder if there is any lightweight solution ?

I use universal-ctags+counsel-etags.

Then you need to press Ctrl+] on the variable to go to the definition of this variable. However, the vscode can pop up the definition when you put the mouse on this variable, this is amazing.

Mouse will drag down my speed.

I know this feature. It's not new to me. It's doable in Emacs, maybe some ivy-postframe api need be used.
