Depends. Back in the day, I worked on development tools for a commericial avionics flight management computer. The headcount for embedded hardware/software verification was greater than for development.
That was never true for software development in other domains I worked in i.e. Fortune 500 enterprise tools, compiler/design tools, networking, and semiconductor.
