getting an fatal error while adding osc circuit

You have a V2 forced V(Saw) to 0V, and Behavorial R with a formula which calculate R = INF at very beginning… add a +1p to ensure not reaching INF.
Press B three time can give you Behavorial R symbol, it is not necessary but it easy to read what it is from schematic drawing.

hey thank you so much ok it might be time for me to learn qspice more thoroughly lol. also @KSKelvin this circuit is part of lm2596 of How to IC Modelling - QSPICE - Qorvo Tech Forum if you can resolve that i can learn more from that.
I aware about that. The challenge is that the schematic is quite pick and the model is implemented with number of formula, it hard to digest and possibly that giving hard time for community to help.
Is that schematic a conversion of something that work in other SPICE platform? Do you have its original netlist
I can quickly response to this one as you simplifed your focus area and explained what this section is expected to achieve.
it is originally from ltspice, i try to migrate my simulations first on my simpler large model circuit and it works fine but this bjt ic model level when i try in qspice it is quite challenging due to unfamiliarity. again, i would like to know how to resolve the problem and might be all in using qspice. here the files from ltspice i try to simulates in qspice:

it is .zip in form of .txt
