.dml files

Neha Anu

Hi all,

I'm new to the tool Allegro PCB SI.I came across the word .dml files.Can anyone please explain

  • What are dml files?
  • What is its importance?
  • What is the difference between dml file and .ibs file?

Regards,

Neha

  • DML file contains model information - it's Cadence's version of the ibs (earlier versions of the tool couldn't handle native ibs) file.  One DML can contain several espice and ibs models i.e. one dml for all components in a design.  Difference can be seen by openeing the dml and ibs in your favorite text editor.

  • DML stands for Device Modeling Language. It is the PCB SI modeling format for everything but interconnect which uses IML. It is a superset of IBIS and handles behavioral models. If you do open it in a text editor, you'll notice that it is lisp-like making it more machine-friendly.
