Spacing Csets in constraint manager

rliang
In the constraint manger is there any way of automatically assign referenced spacing CSET to the objects using the same name (defined by NET_SPACING_TYPE properties in the schematic)?  In addition, is there any way of exporting/importing only the spacing constraints?  I am trying to find a way to automate spacing constraint table creation.  My idea is to have designers import in a table of predefined spacing constraints, and have engineers add the NET_SPACING_TYPE with names to the one defined in the table.  When the logic is imported, the spacing constraint table is populated by tying the referenced Spacing Csets to the objects using the same name.   This way, the designer won’t have to manually entering the information on the spacing constraint table, thus eliminating any potential human error. Thanks.

 

  • There is a third party piece of software called Makecap that allows you to set constraints in a Capture - Allegro flow. Alternatively allow your designers to have access to set the constraints directly. Once a netlist is imported you can cross probe and select nets in capture, the net then highlights in pcb editor and constraint manager if open.
