How to use DPI systemVerilog to detect a substring match?

Question

How do I use SystemVerilog DPI to check if some string contains another string? For example, strstr() in C can detect "str" is contained within "string".

Answer 1

Not sure what you mean by DPI systemverilog? If you want to use functions similar to C functions, then I would highly suggest the svlib library by Verilab. It provides string manipulation methods using the Str class

UVM has regexp string methods built in. It's widely supported and optimized.

You want "uvm_re_match()" to do exactly what you want.
