Hi,
I think of VDSAT and VGS-TH as two different parameters. VGS-VTH is the overdrive voltage available to me while VDSAT is the voltage that signals the onset of saturation.
Having VGS-VTH < VDSAT means you are operating your transistor in weak inversion/moderate inversion region.
As a rule of thumb, you could also annotate your gmoverid to see if it is > 15. This value might differ for your technology, but it gives a feel for you on where you are operating your transistor.
Can you post the picture of the circuit, you are trying to simulate ? Also, May I know why the W > L ?
