Hi, I am able to enter verilog mode in emacs using esc +x, verilog-mode command. My requirement is: "IF I INCLUDE/REMOVE A PORT IN THE PORTLIST OF A MODULE DEFINITION, THE NEW PORT LIST SHOULD GET REFLECTED IN THE INSTANTIATION OF THIS MODULE". I read the functions in verilog mode and but not sure which one serves my purpose. Please advice on how to proceed. Thank you, Harini S Parthasarathy
