"The current verification tool for #ACSL is #FramaC. It also implements a sister language, ANSI/ISO C++ Specification Language (ACSL++), defined for C++."

last time I checked, C++ was left out, only C was supported — times have changed?

now I wonder where #Rust is in the process — there seems to be an ongoing work but nothing that would stand out yet

for #Ada there is #SPARK

https://en.wikipedia.org/wiki/SPARK_(programming_language)

and #PSL is actually independent from the HDLs, can be added on top of VHDL, SV, or Synthesizable #SystemC as well, though the implementations are uncertain

p.s. #Accelera good, IEEE bad
