QRC Extraction Error (FLTTDTA-109002)

jaw500

 HI, I'm trying to perform PEX using QRC (EXT10.1) for a small custom design created in Virtuoso (IC6.1.5) using a commercial PDK. I've been following the guide that came with the PDK for performing DRC, LVS, PEX. It has passed DRC and LVS fine using Mentor Calibre (2011.4) however I get the following error in the QRC log:

#==========================================================#
# Flatten net file, routing, via and device layers
#==========================================================#

SAVEDIR=`beginFlattenInputs`
export SAVEDIR
/bin/mv -f NET h_NET
flatnet -V -li -h '/' h_NET NET
flatnet took 0.00 user, 0.00 sys, 0.00 elapsed, 5884.0 kbytes
netprint -V -N1 power_list:power_list_nums NET
flattenTransistorData \<ENCRYPTED_0LAYER_06154\>-118 meters
sh: ENCRYPTED_0LAYER_06154: No such file or directory
sh: ENCRYPTED_0LAYER_06154: No such file or directory
ERROR (FLTTDTA-109002): Forked flattub command failed.

ERROR (LBRCXM-609): Bad return status from RCX run. 0xff00

INFO (LBRCXM-709): *****  QRC terminated abnormally  *****

 Has anyone come across a similar error before or could suggest anything to try?

 Many thanks in advance for your help.

James.

  • James,

    OK, but you can still report this to Europractice, and they in turn will contact us (Cadence) if necessary (quite likely to be necessary in this case). That's the best bet.

    The fact that it's talking about a layer called "ENCRYPTED_LAYER0..." might give a clue, but that might just be a name chosen in the LVS rules, so not sure. There are others in Cadence who have a more in-depth knowledge of this flow than I do, so I'd defer to them - and that's another good reason to go via customer support, even if indirectly as you're from a University.

    Best Regards,

    Andrew.
