For someone not versed in the specifics of chip engineering, what is the "physical IP"? Is it the process and how the wafers are made?

- j1vms 10y agoARM's IP (intellectual property) consists of designs (that is, layouts) of ARM CPUs, SoCs, etc. It would very likely not include semiconductor manufacturing processes to achieve a final implementation of said design, though I may be incorrect on this point.
- BooneJS 10y agoIf Soft IP were VHDL or Verilog files, then Physical IP is result of the physical design of those hardware descriptions into a database for base layer and masks.
- bedros 10y agowhen designing SOC's you write your IP in verilog or vhdl, however high performance IP such as a CPU are designed specifically for certain chip process, (Intel's 10nm or TSMC's 16nm) and you don't get it in source code (verilog) instead you buy the physical IP (sometimes call hard IP) which is literally bolted to the die next to your design and wired with your design. So, if I'm designing mobile SOC and need 2Ghz CPU in my SOC design, I check with Intel or TSMC to see if they have HardIP of that CPU that I need.
