Cadence RCX - QRC help

cadence rcx

Hi all,

I am working on two verification flows from DRC to PEX; the first flow
is full Assura flow (DRC, LVS, and RCX), and the other flow is:
Calibre DRC/LVS -> Maping SVDB data through qurey server -> Run QRC.


What should be expected is to have the same output SPICE netlist out
from the two flows, or even with slight changes due to parasitics..


The problem i face is: In Calibre/EXT (Calibre/QRC) flow, when data
coming from the query server passes by QRC, the netlist suffer a
strange changes in:
- Device names (i care more for MOSFETs)
- Some net names are changed as if it's trying to rename nets that
comes more than once.
e.g. Mxxx A B C B ----------> Mxxx A B_32 C B (on of the B's were
renamed!!)
- There's some swapping in pins orders (e.g. Source and drain
connections)


How can this problem occure from??


I'm running QRC from command line as:
>> qrc RSF_rcx


Where RSF_rcs contains RCX runtime settings ( avParameters and rcxParameters ) ...

Anyone have idea about the reason for that??
Thanks a lot in advance,
Ahmad
