How can a tech giant 'build' a smartphone chip without its own foundry?
Money, knowledge, and engineering can't replace manufacturing. Or can it?
At the heart of this revolution lies the System on a Chip(SoC), a single integrated circuit that houses the CPU, GPU, modem, and a host of other specialized processors. Hardware Description Languages (HDL) like Verilog or VHDL are used to "program" every behavior of the chip's circuits: every transistor, logic gate, and even the connections between them all.
