silver : SIL test environment DLL

Dear,

I'm working on Vitesco, which provides BSW to my customer hyundai-transys.

Hyundai-transys makes application SW and my company provides base SW, and hyundai-transys sell the integrated ASW+BSW to OEM.

Hyundai-transys is using silver, and they requested to us to provide DLL for SIL and HIL environment.

I'm curious whether it is correct that we provide DLL for silver. And how can we do it.

Can Methworks provide DLL for silver to Hyundai-transys which has silver license?
