Code Example
In VHDL-AMS, a design consists at a minimum of an entity which describes the interface and an architecture which contains the actual implementation. In addition, most designs import library modules. Some designs also contain multiple architectures and configurations.
A simple ideal diode in VHDL-AMS would look something like this:
-- (this is a VHDL comment) 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; -- Saturation current af : real := 1.0; -- Flicker noise coefficient kf : real := 0.0); -- Flicker noise exponent 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; -- Thermal voltage at 300 K begin i == iss * (exp(v/vt) - 1.0); end architecture IDEAL;Read more about this topic: VHDL-AMS
Famous quotes containing the word code:
“Motion or change, and identity or rest, are the first and second secrets of nature: Motion and Rest. The whole code of her laws may be written on the thumbnail, or the signet of a ring.”
—Ralph Waldo Emerson (1803–1882)
“Many people will say to working mothers, in effect, “I don’t think you can have it all.” The phrase for “have it all” is code for “have your cake and eat it too.” What these people really mean is that achievement in the workplace has always come at a price—usually a significant personal price; conversely, women who stayed home with their children were seen as having sacrificed a great deal of their own ambition for their families.”
—Anne C. Weisberg (20th century)
