run Calibre PEX with PCElls

Mohellayali82

 dear all

i have an issue when running calibre PEX for parasitic extraction, it fails and i have this message error 

*Error* load: error while loading file - "/server2/home/WORKDIR/myp/skill1.il

and this happens with all the pcells i created , the way i load them is by putting a load in the libInit.il

 

my layout looks good but Calibre crashes with those errors

 

so my question is what may cause this

 

and as the tapeout is close i am afraid i send a wrong thing to the foundry

creating a GDS2 file successfully and communicate it to the foundry is it enough to transmit my design faithfully, or shouldi take precaution like flattening my whole design

 

please enlighten me

 

regards

  • dear all 

     

    i managed to solve my problem

    however i would appreciate any comments from yours

     

    so my problem wasnt with the pcells but the auCore.cxt as said by the CIW

    so the reason is that   CDS_AUTO_64BIT was set to "ALL" and under the location

    <inst_dir>/tools.lnx86/dfII/etc/context/64bit there is no such auCore.ctx file.

    dost it mean that its impossible to run Mentog Graphics Calibre in 64bit ? that seems terribly frustrating

     

     

    and also in the CIW window i still have this pcDefinePCell undefined function error message, i am puzzled , should i pay more attention to this  message or just dismiss it knowing that every thing looks fine ?

     

    many thanks

  • It probably would help if you gave the exact error message  (so we know which undefined function it is complaining about, to know if it's really an issue or not).

    The auCore.cxt file problem is presumably because of the interface trying to produce a CDL netlist, and auCdl netlisting was not supported in 64 bit mode (it is from IC614 onwards, when the entire virtuoso suite is supported in both 32 and 64 bit mode).

    Regards,

    Andrew.

  • Hi Andrew,

    Thank you for your reply

    For the auCore.cxt you are right because the extractor performs an LVS before so use the auCdl function to generate the schematic netlist, for that i switched to 32 bit version and i am happy with that for now

     

    about the pCell error message, here is the complete transcript:

    i did a simple StreamOut, the stream file seems OK, and whithin my SKILL code i use no printf function nor any forbidden function, all i am using is rod and db functions

    so as you can see its just complaining about pcDefinePCell nothing else
     

  •  The problem is that you're loading the code which defines the pcell each time from the  libInit.il and you should NOT be doing that. When a pcell is defined, the code for it is stored in the database - and it's not necessary to redefine it each time (this is just as well, because it would require write access to the library otherwise). You do however need to ensure any SKILL functions that you define which are called from within your pcDefinePCell() "body" are defined from the libInit.il

    So you need to ensure you are not calling pcDefinePCell() within the libInit.il or within any file loaded from the libInit.il

  • The error message is gone now

    Thanks a lot for the explanation Andrew
