HI,

The IBIS model is not provided as an open source.
I’m sorry I couldn’t help you.

Thank you

Well providing it as “an open source” is up to Wiznet; while, “others do provide”.

As I see it, anyone who worries about appropriate integration would need them.

Thanks,

gorka

Thank you for your response.
So, then, do you have any non-opensource ibis-model (ex. can only access by buyer of mass-production)?
