What's Good About DEHDL’s Variant Editor? 16.6 Has Several New Enhancements!

Comments(2)Filed under: SPB, ConceptHDL, Allegro, Schematic, Allegro Design Entry, design, Grzenia, Allegro 16.6, 16.6, Cadence, Cadence Design Systems, varient editor

The recent 16.6 QISR-2 for Allegro Design Entry HDL has new capabilities for the Variant Editor.

Read on for more details…

Dynamic Viewing of Variants in the Schematic Editor

A new toolbar and menus have been added for viewing variants:

All available variants for a design are listed. It’s easy to switch between any of the variants as well as base views. Selecting a variant will lead to the annotation of variant-specific information on schematic sheets:

  • Properties
  • Do not install
    • Option to cross out

Custom Data Included

A complete hierarchical schematic now includes occurrence-specific data and cross-referencer data. The plotting / PDF publishing of any of the variants contains the complete data.

User-defined properties / custom text can be assigned to variant-specific data in the Variant Editor, and the placeholders on the schematics are updated with variant-specific data.

The attributes form displays the variant name in the source column for variant-specific properties:


Schematic Custom Annotations


  • Option on DNI components
    • Cross out
    • DNI property
    • All properties visibility
  • Color customization
    • Variant-specific component   
    • Variant-specific properties
    • DNI component   
    • DNI cross


When you save a variant in the Variant Editor it generates files specific to each variant containing variant-specific information, and files are used for dynamic display of data in DEHDL schematics. Variant details can be defined at the time of creating a new variant or editing existing variant details:
–    Variant name
–    Variant property name-value to be annotated on schematics
–    DNI property value
–    Variant-specific custom text values

I look forward to your feedback!

This was a sorely-needed feature for Variant Editor that works great! If you're creating variants, you will want to take advantage of this to properly document variant schematics. Is it now possible to generate these variant schematics using the PDF Publisher tool? Creating variant schematics is still an inexcusably painful, convoluted process, but these updates provide much hope that the entire variant flow will see similarly wonderful enhancements.

Thanks Evan! Glad this will be useful for your design environment. You can select a specific Variant and then use PDF Publisher to make the PDF file.
