Aside from using it, +the goal and its purpose is that +developers should under no circumstances have to know +that their HDL, which was initially written as scalar +nmigen HDL, is behaving entirely transparently as full +SIMD capable HDL. There are a few caveats to that: some +capabilities such as LHS assignment to an ast.Part are so +complex in a SIMD context that SimdSignal in its first +version does not implement it.
