Vhdl-ams beginner

Behavioral Modeling with VHDL-AMS (same course available in other regions). Also for books:

The System Designer's Guide to VHDL-AMS: Analog, Mixed-Signal, and Mixed-Technology Modeling (Systems on Silicon... by Peter J. Ashenden, Gregory D. Peterson and Darrell A. Teegarden (Sep 18, 2002)

and:

VHDL-AMS : Applications et enjeux industriels (French Edition) by Herve

or (in English):

VHDL-AMS by Yannick Herve (Mar 1, 2006)

There are also tutorials on AMS Designer in the documentation, which have more of a tool focus.

Hello Sebastien, 

To create the ideal comparator in vhdl-ams is quite simple and straightforward.

• The code should be something like this (depending if you want to have threshold or not).

You can find the full code, test bench and simulation results on the source: ideal comparator  

entity comparator is 
GENERIC(
Vthres : REAL := 0.1 --threshold
); 
PORT(
TERMINAL Vin : ELECTRICAL;
TERMINAL Vref : ELECTRICAL;
result : out std_logic
);
end entity comparator;

ARCHITECTURE vhdlams of comparator IS 
QUANTITY Volt ACROSS Vin TO Vref;
BEGIN
--result <= '1' when (Vin > Vref) else '0'; --without threshold
result <= '1' when Volt'above(Vthres) else '0'; --With threshold 
END vhdlams;
