一些ant.rule的问题

Ethan.Zhu

用calibre带入ant.rule检查出一些问题，看不懂error说的是什么意思，请各位大佬帮帮忙


1.）A.R.MIM.5.M3_CBM_B { @ Mx as MIM capacitor bottom metal directly connecting to OD/gate
                   @ through underneath VIA is not allowed
  NET AREA RATIO CBM3 SD > 0
  NET AREA RATIO CBM3 GATE > 0
}


2.）A.R.2_A.R.3.M4 { @ (M4 perim*thickness / gate area) > 400 (without effective diode)
                 @ (M4 perim*thickness / gate area) > Ratio (with effective diode)
  NET AREA RATIO M4 M4_MIN_DIO GATE > 0         // no effective diode
    [
      !!AREA(M4) * !!AREA(GATE) *
      (!AREA(M4_MIN_DIO) * ( PERIMETER(M4)*M4_THICKNESS/AREA(GATE) - 400 ) +
      !!AREA(M4_MIN_DIO) * ( PERIMETER(M4)*M4_THICKNESS/AREA(GATE) - AREA(M4_MIN_DIO)*400 - 2200 ))
    ] RDB A.R.2.M4.rep M4 M4_MIN_DIO GATE
}



3.）A.R.MIM.5.CTM3_M4_CTM {@ Unbalanced structure is not allowed.
  A = STAMP unBAL_CTM_CTM3_M4 BY CTM3
  NET AREA RATIO A M4 > 0 [!!AREA(M4)*AREA(A)]   
}




4.）A.R.MIM.5.CTM3_M4_CBM {@ Unbalanced structure is not allowed.
  A = STAMP unBAL_CBM_CTM3_M4 BY CBM3
  NET AREA RATIO A M4 > 0 [!!AREA(M4)*AREA(A)]
}
