Hello,
i've been trying to write a PSpice netlist for the schematic provided but have been unable so far to get it working.

Could anyone help me with the netlist ?

Thank you very much.

You can add your own spice models in LT spice that is no problem at all. I am sure you can find some tutorial. Just use Google

Hello again,

i've been trying to get it working but so far no luck.Here's what i've come up with.
Complete PSpice .cir file with LM13600 model included and a schematic with node numbers.
But i still wasn't able to get the corresponding triangle/square outputs and i'm not sure why.
