Hi lacy,
I downloaded the spice model from zetex website @
http://www.zetex.com/3.0/spice/zxct1080.mod and also, the full zetex product range spice
model can be downloaded from  http://www.zetex.com/3.0/spice/zmodels.lib.
I have emailed their spice department regarding multisim, hopefully they
will reply soon
