Resistor value in the "tsmc13rf PDK" regarding auCdl parameter

deepbluesea

The resistor value of "CDL out" netlist is not the real value
5 n6 T) ^/ W0 H7 Z1 ]when I use TSMC 0.13rf PDK

; J& `) A7 {4 V& c# L( VI use tsmc13rf PDK.
( [8 N, {: C, L. o0 }When I CDL out from CIW window, the output value for the resistor as below:
" W" c: m+ C2 X( |5 J0 nRR1 res_in res_out 15.34 $[PS] M=1
But the real value is 14.8213 shows on the schematic.
6 H+ [, d7 K# o* L3 D7 hWhy on the auCdl CDF parameter they choose the simple value to be output on the netlist?
We want to see the real value, this will comfuse people when they doing verification.
8 J4 m( a9 _" r$ U0 pI can't turn on  the "Accuracy" switches when I run Assura lvs.
; t( F/ H0 h* oI still pass LVS, but I am just curious why they do that on the CDF parameter.
