VHDL tends to reign in European hardware companies.

And Japan, I'm told.

I wonder why there aren't many successful European hardware products.

I would assert any company that doesn't go bankrupt is successful, doesn't need to be late stage capitalism.

Other than that, Nokia until Microsoft placed an agent on it, Phillips that contributed to CDs, ASML...

Three is not many

ST, Infineon, ARM(!!), NXP, Raspberry Pi Holdings, Nordic Semiconductor (original developers of AVR, now known for Bluetooth chips and auch)...

" any company that doesn't go bankrupt is successful"

Well, VHDL was heavily based on Ada.
