That number is why most hardware startups never see their own silicon. But the economics changed at the older nodes: with an open PDK such as SkyWater SKY130 or GlobalFoundries GF180MCU, a small team can push real RTL through place-and-route, DRC, LVS and stream out a GDSII file for a few thousand dollars in shuttle fees. The toolchain that makes this possible is fully open source — and it is the same stack used on silicon that has actually shipped.</p>
