This paper discusses 3 critical facets of the Arm ecosystem: design verification, physical design, and software development. Each one directly affects the time required to develop a complete SoC and software stack. Whereas Arm and its partners offer a wide set of tools and support, some other CPU ISAs fall short in these areas.
