heHiCreateInst() error message in sub-version IC6.1.5.500.10

lkokkalas

 I try to create an instance in the current layout window.

 envSetVal("layout" "instLibName" 'string "myLib")
 envSetVal("layout" "instCellName" 'string "myCell")
 envSetVal("layout" "instViewName" 'string "layout")

 cdfSqu = cdfGetCellCDF( ddGetObj("myLib" "myCell"))
 change cdf values ...

 leHiCreateInst()

The first time, create instance form appears and the cell is placed in the layout. When I try this again 

X Toolkit Warning: Select failed; error code 9

appears in CIW and  create instance form does not appear. It seems to work fine with sub-version  IC6.1.5.500.6

 Any ideas?

Thanks

  • Please check the latest hotfix (which is IC6.1.5.500.132 - ISR13) and if it's still an issue, please contact customer support. I couldn't find a report of this.

  • Hi Andrew,

    thanks for the reply.

    The error message was finally not caused by leHiCreateInst(). 

    In our environment (RH4 ) an OS setting for the "max number of concurrently open files" has been changed from the default value of 1024 to DOUBLE its value - 2048. This allows more files to be opened concurrently by any user.

    In Cadence file descriptors are monitored through standard "select" operations .The "select" system call is only capable of monitoring a limited number of file descriptors. "select" 's file handling capability limit is currently set by the __FD_SETSIZE flag, which is hardcoded in linux to 1024.  Setting the OS level limit to 2048 has inadvertently "broken" Cadence's ability to handle multiple I/O operations, through "select" system calls.

    Our skill program makes extensive use of I/O operations and we were able to see this error message.

     Regards,

    Labros
