I love that VHDL formalizes Verilog's pragmatic blundering, but emphasizing delta-cycle ordering is "inside baseball" and IMO bad marketing. VHDL's approach is conceptually clean, but from a practical perspective, this ordering doesn't (and shouldn't) matter.

Better to emphasize the type system, which make a durable and meaningful difference to users (both experienced and new). My go-to example is fixed-point arithmetic: for VHDL, this was an extension to the IEEE libraries, and didn't require a change to the underlying language (think of how c++'s std:: evolves somewhat separately from compilers). Verilog's type system is insufficiently expressive to add fixed-point types without changes to the language itself. This positions VHDL better for e.g. low-precision quantization for AI/ML.

In any case, the VHDL/Verilog language wars are over, and while VHDL "lost", it's clear the victory was partly Pyrrhic - RTL probably has a polyglot future, and everyone's waiting (with mixtures of resignation and hope, but very little held breath) for something better to come along.

VHDL mostly lost the ASIC consumer market and for some that's the only market that matters, but the hardware design ecosystem is much bigger than that.

I wonder what AI will do to RTL/verification, the rigid nature of VHDL may be a better target for AI than Verilog.
