[Iverilog-devel] 'image attribute

[Maciej S. <mac...@ce...>]

Hi,

I am wondering what would be the right way to implement VHDL 'image
attribute, which returns a string representation of a variable.

The first idea is to use SV $sformatf system function, which returns a
string based on the formatting string (e.g. "%d" and input data, but it
is currently not available in Icarus. I could add it, but as far as I
know, the VPI standard does not allow to write functions that return
strings.

What's your opinion? Should I extend VPI in Icarus to allow returning
strings or is there another, more elegant solution to the problem?

Regards,
Orson
