The 16.6 Allegro PCB Editor release provides enhanced Object Filtering to control object display in the Constraint Manager (CM) Worksheet. This feature enables you to select and filter out objects that you want displayed in the CM worksheet.
Read on for more details…
The objects for diff pair model sub-filters are in the same Filter dialog as a tree. The main level of the tree contains existing object types. Sub-filters are available in the tree control as leafs:
The "Advanced Filters" pane has three new checkboxes representing “Global,” “Interface” and “Local” objects. The checkboxes are available only in the front-end (Allegro Design Entry HDL – DEHDL) integration of CM. Here’s the Filter dialog:
The sub-filters are object-specific and are displayed under the objects they belong to.
Nets of XNets sub-filter controls the Nets of XNets display, is straightforward and represents exactly what you see.
Zero/One Pin sub-filter allows filtering out zero / single-pin nets.
Voltage sub-filter filters out voltage nets (VOLTAGE property set). This sub-filter will be enabled only in the Properties / Net / General Properties worksheet. In the rest of the worksheet it’ll be greyed out and unchecked. It’s a good reminder indicating the “Electrical worksheet is not showing Voltage Nets.”
Model-defined sub-filter will filter-out model-defined differential pairs.
Library-defined sub-filter will filter-out library-defined differential pairs.
Schematic-defined sub-filter will filter-out schematic-defined objects (only in DEHDL).
Is used as a super-header and covers three object-related columns:
The object type.
Stands for “suffix” or “sub-type.” This column will show “G” for Global objects and “I” for Interface objects (for DEHDL only). The same column includes “sub-types” for existing differential pair “Model-defined” (M) and “Library-defined” (L) objects.
Shows the Object Name.
New column for suffixes in the CM UI
Right mouse click on each of the columns to see the options.
For the “Objects” super header the menu contains two items:
For the “Type” and “S” columns the menu contains three items:
For the “Name” column, the menu corresponds to the pre-16.6 menu for the “Object” column:
As always, I look forward to your comments on using these new capabilities.
