How to increase the tolerance of capacitance in Assura LVS?

Dear Community,

Can anybody help me with this issue:

I want to increase the tolarane of CAP1 ,but no value does affect on result.

In compare.rul file it is described this way:

compareParameter("CAP1" compCAP1 ),

while compCAP1 is a procedure:

procedure( compCAP1( lay, sch ) ; checks props: value

  prog(( )

        terrormsg = ""

    modelName = lbcGetModelName( lay sch )

    compCAPmod( lay, sch )

    compCAPmodWL( lay, sch )

    if( terrormsg == "" then return( nil )

    else

      return( terrormsg )

    )

))

Additional description of CAP1 seems has no effect on result.

compareParameter("CAP1" percent("c" 200 ))

Can you please help me to understand this syntax ,as I am new to assura and it’s  a black box for me yet.

Thanks in Advance,

Shushanik
