m/matl – The EM Technology File Editor for RFIC

 

Mühlhaus GmbH has created a new material file utility to help RFIC users with the setup of complex stackups. The tool is available to Mühlhaus Consulting & Software GmbH customers at no extra cost.

m/matl – cross section view (click for full size)

semi-proportional view (click for full size)

 

m/matl creates material files for the Cadence and Agilent interface, as well as Sonnet *.son project files along with the layer mapping files.

You can define stackups starting from an empty file, or import existing files in Sonnet *.matl format, Sonnet *.son format and Agilent *.slm format.

The stackup can be visually inspected in different views. Material data input can be in Sonnet format (thickness and conductivity) or the data as typically specified in foundry data sheets (thickness and ohm/square).

Dielectric layers can also be merged, creating a new dielectric with the total height and the effective epsilon, or splitted into multiple pieces.

Current version: 02. March 2012
m/matl version 2. March 2012 (zip, 1.7MB)

  • Support for multiple metals on the same level, with proper visualization
  • Import *.son model
  • Export *.son model for stand alone use
  • Manage and export layer mappings for GDSII and DXF workflow,
    to enable multi-design-flow support from a single source file

4. Nov. 2011

  • Drawing now side by side with material grids
  • “Edit” from cross section view now brings up editor dialog, instead of switching to metal/via/dielectric tab
  • Vias on adjacent layers are now aligned if they have the same layer name
  • slm import: Fixed mistake with incorrect target layer for thick metal expansion down
  • slm import: Fixed error with via span for thick metal, expansion down
