The core of the agreement, presented at a joint event on Wednesday, will be to ensure Siemens tools that are used to design everything from chips to factories will ultimately be able to feed data to Nvidia’s virtual-world building software Omniverse to create more photorealistic visualisations. 

“The digital twin is physics-based. It doesn’t just look like the real thing, it behaves like the real thing,” claimed Siemens CEO Roland Busch. “This is not about animation but simulation. If you don’t mimic the real world accurately, you don’t get the benefit out of it. The digital twin has to be comprehensive.
