VHDL-AMS is a historical programming language created in 1993. VHDL-AMS is a derivative of the hardware description language VHDL (IEEE standard 1076-1993). It includes analog and mixed-signal extensions (AMS) in order to define the behavior of analog and mixed-signal systems (IEEE 1076.1-1999). The VHDL-AMS standard was created with the intent of enabling designers of analog and mixed signal systems and integrated circuits to create and use modules that encapsulate high-level behavioral descriptions as well as structural descriptions of systems and components.VHDL-AMS is an industry standard modeling language for mixed signal circuits.

Example code from Wikipedia:

library IEEE;
use IEEE.math_real.all;
use IEEE.electrical_systems.all;

-- this is the entity
entity DIODE is
   generic (iss : current := 1.0e-14;  
            af  : real    := 1.0;      
            kf  : real    := 0.0);     
   port (terminal anode, cathode : electrical);      
end entity DIODE;

architecture IDEAL of DIODE is
  quantity v across i through anode to cathode;
  constant vt : voltage := 0.0258;     

  i == iss * (exp(v/vt) - 1.0);

end architecture IDEAL;
