Pspice model compatibility

A simple NAND test circuit as follows:
QSPICE results:

LTspice results:

Pspice results:

Change NAND gate to the builtin NAND gate of QSPICE, result as follows;

Is there are something wrong for spice syntax compatibility?

It’s probably because QSPICE gates require power and the logic threshold defaults to halfway between VDD and VSS. Other SPICEs don’t do that.
