Material Library File
The physical properties of materials (electrical, magnetic, thermal, structural, and so on) are
essential in analysis and simulation of chip/package/board designs. A company can store its
material libraries at a central location so that everyone can use the same properties of
materials. In addition, a team or individual users can store their own material libraries at a
specific location so that they can have their private material models and perform what-if
analysis of materials.
Cadence provides a library of materials in an xml (.cmx format) file that is used across
various Allegro and SIGRITY tools. The material library, by default, lists 134 materials with
the following supported types:
■ Metal
■ Dielectric
■ Thermal
■ Magnetic (Ferrite)
■ Structural
You can edit the material properties, as per your requirements.
Data in the material library is organized into the following parent elements:
■ The DataDescriptions Element on page 6
■ The Material Element on page 8
■ The SurfaceRoughness Element on page 15
