SPICE model not working with Altium Designer

Q

We want to use some of your multiplexers for a device and have to simulate the
circuit in front (with Altium Designer). Therefore we took your Spice models
and tried to simulate. Sadly even in a test circuit the multiplexers doesn't
work in the simulation. For comparison we took different MUX-Spice models from
you and also one from maxim integrated (which instead worked as excepted). Are
there any additional restrictions with your models or something else which have
to be looked at? Are updated models available?

A

our SPICE models are tested and developed for Multisim and ADIsimPE simulation
tools. If you would like to verify your design using ADG779's model, you can
download a free version of ADIsimPE on our website. For your reference I am
attaching the link below.

Other simulation tools may have a different syntax.
