Current statistics show that up to 70 percent of a system on chip (SoC) is now comprised of third-party IP and homegrown IP that was re-used from previous chips.
There are several very good reasons for this trend. First, it’s far quicker to integrate and modify existing IP blocks than to build them from scratch. Second, it’s often a safer bet that IP, which is tested in the market and approved for manufacturability by foundries, will work as planned. And third, it usually costs less to buy or license a functional IP block than to build one.
