Memory fault Assura RCX

Campo85

Hi all,

I have some trouble with parameter extraction with assura RCX. When I run the RCX in Assura ( after the LVS ), the parameter extraction fails with this error : 

 

/home/stefano/Project/TSMC_Projects/Dice/run_assura_lvs/FF_DICE/rcx.sh: line 695: 11121: Memory fault

sh: line 1:  8232 Segmentation fault      /home/stefano/Project/TSMC_Projects/Dice/run_assura_lvs/FF_DICE/rcx.sh 2>&1

*WARNING* Bad return status from RCX run. 0x8b00

 

I have this in syslog :

pax16[11121]: segfault at 0000000000000000 rip 0000000008098e38 rsp 00000000ffd0b830 error 4

 

 Can anyone help me ? Thanks in advice for any reply.

 

Best Regards

Stefano. 

  • Hi Stefano

    It looks like you are still using the out-dated RCX instead of QRC for parasitic extraction. The memory fault can most likely because resolved if you switch to QRC. Would you please give it a try? Please download PVE 11.1.2 package from the downloads website.

  • Hi Stefano,

    I had had the same problem last week, however with a different PDK.

    In my case I tried to extract a complete chip, including pads. As it 

    turned out I had to preserve the pad cells during the assura and the qrc run.

    Maybe you have  a somehow compareable problem in your design

     

    Best Regards

  • I don't have any problem with the layout because I have already extracted the same layout on a different PC. I think that it is an installation problem. I remember that when I was able to extract, the extraction was made by QRC and no RCX.. My pc don't have the QRC extraction, that's the problem. Best Regards Stefano

  • Hi all, 

    I've installed the QRC ( EXT101 ) and now it works. Thanks to everyone.

    Best Regards

    Stefano
