Problem using QRC with Calibre input

mbhealy

 Hi All,

 I'm trying to use QRC to provide me with SPICE netlist output using Calibre LVS inputs.

 I have tried to follow the QRC with Calibre Input section of the QRC user guide but I've run into a problem.

 I'm getting the following error:

 INFO (LBRCXM-630): Starting extraction...

ERROR (AGDPRP-31023): syntax error in file ./query_output/Design.lph, line 2

;|INFO (RCXSPIC-27150): The following forked command failed. Contact Cadence Customer Support for assistance.
 agdsPrep -V -rundir ./query_output -outdir ./qrc_run -e ./techdir/lvsfile:Design.alm,Design.ilf -pl Design.ports -mcell ./qrc_run/Design.hcl -d Design.devtab -prefix ./qrc_run/prefixfile -l ./techdir/lvsfile -i Design.ixf,Design.lph,Design.sph:Design.gdx -n Design.nxf,Design.stl:Design.gnx -s Design_pin_xy.spi:Design.xcn,hccidtmfile

 When I try to run the forked command 'agdsPrep -V ...' as a separate run I get  a licensing error:

 ERROR (LBLIC-14003): Neither one of the following required licenses are available:
  (Virtuoso_QRC_Extraction_XL + QRC_Advanced_Modeling) or
  (Encounter_QRC_Extraction_XL + QRC_Advanced_Modeling) or
  Virtuoso_QRC_Extraction_GXL or
  Encounter_QRC_Extraction_GXL.

 

The Design.lph file was created from the Calibre query_output command and doesn't look malformed in any way, so I don't know if that error is spurious and really it's a licensing problem. Unfortunately I can't figure out which product number  QRC_Advanced_Modeling is from our product guide. We have  Virtuoso_QRC_Extraction_XL (QRCX300) and   "Virtuoso Advanced Analysis GXL option" (QRCX310) installed. Does anyone know the product number for QRC_Advanced_Modeling? As in QRCX310 or something? This is for university use if that matters.

 

Thanks!

  •  Quek,

     I created a new calibre run without hierarchy. I generally use the Calibre GUI integrated into Virtuoso. It said that the command used for running calibre is simply: 'calibre -lvs -nowait _master_top_lvs.cal_'.

     Then I reran the query command: 'calibre -query_input query_cmd -query ../lvs_run/svdb core1' and it generated a new query_output. I am using the query_cmd file that was included in the QRC distribution. This query_output directory still has the Design.lph and Design.sph files. The only thing in them now is the header, the body of the files are empty. I tried running QRC with these files in place and it gave me the same syntax error in Design.lph. Then I moved the files and reran and I get a syntax error in Design.nxf.

     When I move Design.nxf and rerun QRC I get the following error:

    Any idea what a unified techfile is and why my techfile is not unified?
