Re: PLI vs DPI

As I know, PLI is the programming language Interface for Verilog;
It is used to connecting C language with Verilog and use C functions in Verilog;

I have no idea about DPI. Sorry!

PLI is more for "design introspection" - i.e. hierarchy walking etc. Where as DPI is to integrate foreign models into SystemVerilog. DPI can't be used to get value of a net for instance, you need to use PLI for it.

Refer to your simulator docs for some examples.

And we cover DPI at length in our SV course(s) in Bangalore.
