@Guardring.II

type guard ring must connect to GND through P+ diffusion

我的电路地是VSS，添加线名字VSS，一直有这个错误，怎么修改呢

cal_drc.rul代码：

// nsd_vdd=nsd node "VDD*"
nsd_vdd=NET nsd "vdd?"
// nsd_not_vdd=nsd andnot nsd_vdd
nsd_not_vdd=NOT nsd nsd_vdd
// psd_GND=psd node "GND*"
psd_GND=NET psd  "GND?"
// psd_not_GND=psd andnot psd_GND
psd_not_GND=NOT psd psd_GND
// guardring_II_err_hvpmos=hv_guardring_p overlap psd_not_GND
guardring_II_err_hvpmos=(NOT OUTSIDE hv_guardring_p psd_not_GND) OR (NOT OUTSIDE hv_guardring_p1 psd_not_GND)
Guardring.I {
   @Guardring.I

type guard ring is necessary for HV NMOS and HV PMOS .
   OUTSIDE hv_gt (HOLES pdiff INNER)
   OUTSIDE hv_n_gt2 (HOLES L88910 INNER)
}
Guardring.II {
   @Guardring.II

type guard ring must connect to GND through P+ diffusion
COPY guardring_II_err_hvpmos
}
