I am using SpiceOpus lite. I am trying to create a voltage source with a temperature dependence. Something on the order of
bsource 1,0 v=(1*temp)
anyone have any luck with this? I know that I can set the temperature with
let @@@temp=100
and can sweep using
dc @@@temp 25 50 5
but SpiceOpus doesn't recognize
bsource 1,0 v=(1*{temp}) or bsource 1,0 v=(1*{@@@temp})

I don't know SpiceOpus, but a work-around that should work with all Spice variants:
Current source driving a resistor, then E-source buffering voltage across resistor... E-source output is the voltage source you needed.
Set your desired TC's in the resistor model.
I note, looking thru some old projects, that I used ETABLE to create the boundary specifications for some 10K PECL designs. If SpiceOpus can do tables, you could implement your voltage source that way.

Jim, Thanks. Right after I send in the question I came to the same conclusion.
