The difference between IC layout design and PCB layout design

Ic refers to integrated circuit, and layout design is the last step of ic design.

The object of pcb circuit board design is macro circuit, that is, to build a system with chips.

Ic design is the chip itself, so the layout here is the physical realization of the internal circuit of the chip. Even the naked eye can't see the circuit clearly because it is too small. General layout tools are cadence's virtuoso.

If it is a pcb, there are many tools.

I'll give you another layout of ic design ~

Of course, this is only a small part of the chip.
