The following figure shows the cdsSpice A2D interface primitive.
The following figure shows the digital destination as a function of voltage sensed.
The cdsSpice and cdsSpice-compatible A2D interface models are macro files containing A2D
interface primitive and optional analog devices. You must use the first parameter (
&1
) of the
macro to inherit the digital destination and the second parameter (
&2
) of the macro to inherit
the interface net. Other parameters of the macro are user-definable.
The following examples are the cdsSpice A2D IE macro models,
MOS1_a2d.S
and
TTL1_a2d.S
.
