How to add all, except one file in iverilog command line instruction from a folder?

Question

I understand that if I want to include all the Verilog files I can do so by adding files like this:

iverilog /Users/kp/Desktop/all_new2/*.v -s testbench.v

which takes all files in all_new2 folder and sets testbench.v as the top module. However, I wish to exclude a file c_functions.v file from this folder. How do I do it?

create a file list and use `-ffile` of `-cfile` quals. – Serge Jun 30 '20 at 10:32 — Serge, Jun 30 '20 at 10:32

One way is to use the -y <libdir> option, which is common among other simulators as well. This is described in the iverilog Command Flags/Arguments document.

iverilog -y /Users/kp/Desktop/all_new2 testbench.v

This will compile only those modules that are needed in the directory. There is no need to explicitly list out all files.
