The hardest part about fabless semiconductor startups is the lack of flexibility to pivot.

The time to design chips correctly is 10x-20x higher than doing the same in c++ (let alone a higher level language).

Example: in my previous company we needed to do some Jpeg decode in hardware. You have to buy a library for that. The library aint cheap so you have to evaluate vendors first, then work with lawyers to negotiate a licensing agreement. Then you design, implement, and test integration into your chip. All of this takes 2-3 man-months.

By contrast, we prototyped it in sw in an afternoon, and could be out the door with tests and production polish in less than a week.

You can use fpgas or low-NRE ASICs like eASIC to reduce the build costs, but engineering hardware is really slow.
