How can i list all hierarcheis of modules/submodules in verilog/system verilog?

Question

I want to view a list of all modules/sub-modules/instances in verilog/system-verilog compilation; is that possible? I know i can do a %m in $display and it will show the hierarchy of that particular instance. I want to get a similar list but for all the modules and instance which I can use for later post-processing. Would this information be EDA tool dependent?

Thanks in advance :)

you can create a VPI application to do it. – Serge Jul 20 '20 at 18:26 — Serge, Jul 20 '20 at 18:26

Most simulation tools provide commands to this either with some kind of report, or creating a simple Tcl script.

You can also do this using SystemVerilog's VPI or DPI/VPI combination so it won't be tool dependent. See my 2016 DVCon paper: Introspection into SystemVerilog without Turning It Inside Out

do you know the command for questa/modelsim? now that I saw this question... I need to know. – fgagnaire Jul 20 '20 at 20:03
`find instances` – dave_59 Jul 20 '20 at 20:59
