Pretty much every high end board is designed under Altium. QSpice is a different tool for a different purpose.
And like I said, those few cases were the length actually matters tend to be heavily assisted with automation as it is.

I guarantee you that an iPhone board isn't an optimal solution, simply good enough.
- Joel_Mckay 1mo ago>I guarantee you that an iPhone board isn't an optimal solution, DFM almost certainly guarantees an iPhone is both form, and cost optimized. Jobs was very clear early on in the product development that the EE work had to be miniaturized due to the energy density possible setting volumetric minimums on the battery technology at that time. > simply good enough. A common philosophy for people that make cost optimized low-end products. Some people love their 3.7kg phone, as it comes with a stylish shoulder strap. =3
- monocasa 1mo agoOptimized != optimal Optimal means there aren't any optimizations possible remaining. Are you seriously going to suggest that there aren't any potential optimizations left in the iPhone's mainboard?
