ADC and DAC Converters VHDL model

[Xabier Iturbe]

Iam designing a system that includes an ADC and DAC Converters. In
order to simulate it, I need the models of the converters, if it would
be possible in VHDL lenguaje. Thank you.

It is possible to model ADC/DAC in VHDL. It has real data type and
necessary procedural constructs for it. However if you want to model
pure analog things like oscialltor, jitter etc. it gets tricky. An
approximate model say using "successive approximation" algorithm is
doable in VHDL. I've done it in the past for a customer of mine, sorry
can't share the source code.

I would write a simple, but cycle-accurate model
of the digital interfaces and use an integer port
to represent the analog pin. Note that some
vendors may have already done this for you.

Depending on the analog content, this might be suitable for VHDL-AMS.

There are some behavioral models of ADCs and DACs at
http://www.freemodelfoundry.com/converters_vhdl.php. They use reals for
the analog ports.
