What I’ve seen is that a product is being designed with both ARM and RISC-V cores. The RISC-V cores outperformes the equivalent ARM cores and have no licensing costs. It’s used if it’s a management core not usually programmed by the customer or specialized low power and/or low latency processing. The ARM cores are used for TrustZone, FPU and DSP functionality and for the extensive IDE, debugging and trace support. I can see RISC-V gradually taking over, since it now has a foot in the door. But it’ll take a long time and depends on third party development.
