Hi, I'm trying to model a circuit with a TPS62933 in it, ti has a pspice model for it. Anyways I get a singular matrix error, so I'm trying to fix the ti model to work with ngspice, so I reduced the problem to this circuit: .title Test schematic .func if(a,b,c) 'ternary_fcn( a , b , c )' V1 POS NEG DC 13.4 R1 POS MID 5k R2 MID NEG 3k R3 OUT NEG 3k E_TEST OUT NEG VALUE { if(V(MID)>7.9,1,0) } .end In that, I get: Note: Compatibility modes selected: ps max line length 118, max subst. per line 1, number...

Fallback to vaCreateImage + vaPutImage/vaGetImage when vaDeriveImage fails
