Hi,
I am trying to simulate TPS543320 based power supply design but I am constantly getting the following error:
ERROR(ORPSIM-16550): Floating point computation failed during matrix solution. Possible solutions: 1)Ensure that all device parameters are in valid range. 2)Try using .options LIMIT
Below is my circuit:

I can't see any obvious error so I would need some help on this. Also, which SW pin has to be connected to inductor - SW_0 or SW_1? When I started simulation for the first time I got message that .subckt name does not match .ends name. Problem was here:
.subckt D2A_CONVERTER_9Bout d0 d1 d2 d3 d4 d5 d6 d7 d8 ref PARAMS: THRESH=0.5
.ends D2A_CONVERTER_9B
I guessed that correct syntax would be:
.subckt D2A_CONVERTER_9B out d0 d1 d2 d3 d4 d5 d6 d7 d8 ref PARAMS: THRESH=0.5
.ends D2A_CONVERTER_9B
Is this right or wrong?
