Can't create devices in layout using pycells

edbewald

I am using IC6.1.5.504 in 32bit mode.  RHEL5, linux x86-64.

 We recently started looking at a kit that utilizes Pycells.  When we place an instance of

a device (ex. nch_mac) none of the layers are visible.  The 'q' form shows the correct

parameters, the layer pallette shows the correct layers.  When I try to stream out, I get the

error, 'translating cellview <path>/layout as STRUCTURE' and no GDS file is created.

Has anyone else seen this and is there a solution?

Thanks,

Eddie

  • Andrew,

     Thanks for your feedback.  I finally resolved the issue basically by 1) reading EVERYTHING I could from the

    foundary, Cadence and Ciranova's website and 2) pure chance. Here is what I did for future reference.

    1) Unzipped 2 imbedded files inside the Pycell directory that contained the layout information.  I could find

    no documentation saying this was necessary and the directory was supposed to be 'self-extracting'.  Why these

    are missed is a mystery.

     2) ALL applications' bit formats (linux, Cadence and Python) MUST agree.  All either 32bit or 64bit.  If any one

    is off, Cadence device creation just fails with no discernable Warning or Error message.

    And that's it.  I'm up and running.

    Thanks again,

    Eddie
