When I CDL out from CIW window, the output value for the resistor as below:8 x: T) n1 C- E
RR1 res_in res_out 15.34 $[PS] M=1 U+ b( x3 {% h3 h/ l: O( ]
But the real value is 14.8213 shows on the schematic.0 |3 [/ k! U9 ^$ U( K
Why on the auCdl CDF parameter they choose the simple value to be output on the netlist?* s& h" d4 ]8 G0 e9 h5 Q
We want to see the real value, this will comfuse people when they doing verification. , N% L0 B; |6 R cI can't turn on the "Accuracy" switches when I run Assura lvs.' g1 f' I+ s; X" @% D j# Q
I still pass LVS, but I am just curious why they do that on the CDF parameter.! \- ^9 |+ W9 x
Anyone in the TSMC or others can explain why?
