I write res model myself as below: .lib r_typ
.model hrpoly r scale=1 tc1=-2.1389e-3 tc2=8.7053e-6 vc0=1.0761e3 vc1=-1.9408e-4 vc2=-1.6639e-4 *hrpoly sheet resistances=1000
.endl r_typ
the temp coeffcient works, but voltage coeffcient doesn't work, is " vc0=1.0761e3 vc1=-1.9408e-4 vc2=-1.6639e-4" right? Thanks .
