I've converted an IBIS model to a SPICE model using microCap, and am trying to simulate that subckt with LTSpice.
Using LTspice, I get an error with the subckt in the library.
"u1:g1: Unknown circuit node: "u1:xvkdr.vkdr" requested in behavioural source"
It cannot understand the V() function used in this way "V(XVKDR.VKDR)" Which is referencing a specific voltage net (VKDR) within the subckt (XVKDR).
Here is the LTspice project with .lib
