LSI design flow and EDA

What does 'IP (IP core)' mean in LSI design?

  1. AAn Internet address
  2. BA reusable, pre-designed circuit block such as a CPU or interface
  3. CThe name of a manufacturing tool
Show answer and explanation

Answer: B. A reusable, pre-designed circuit block such as a CPU or interface

An IP core is a pre-designed circuit block prepared for reuse in other designs, such as a CPU core, memory, or interface circuits like USB and PCIe. Besides in-house development, IP can be licensed from specialized companies, shortening development time for large SoCs.
