Creating Unique Net Names ■ In the allegro_component command (File – Export – Board Level Component), by default, net names are appended with the pin number to make pin names unique. To append 0 padded integers to create unique pin names of equal lengths set the allegro_component_seq_pin_names under Ic_Packaging in the User Preferences. The order of the suffix counters is sorted by the pin numbers. ■ The auto create net command (Logic – Auto Create Net) has options in the Auto Create Net dialog box that allows you to create unique net names. You can select a prefix from Net name Prefix. You can also select a suffix from Net name suffix instead of the tool always using the physical pin number. You can select Use pin number if default value not available to use the pin number as a suffix in case the suffix type specified in Net name suffix is not available. Update Labels In 16.6, information is stored to describe what the text labels created by the dpn (Manufacture – Documentation – Display Pin Text) command represent, be it the die pin name, net name, finger name, or some other value. When you click the new Refresh All Labels button in the Options pane, all text labels with this information are updated so that their text agrees with the current data in the design. In 16.6, if you open a design created in an earlier release, you must recreate the text to be available for intelligent update by dpn. Support for Sub-Stacks in Die Stacks In 16.6, die stacks support sub-stacks, and the notion that two items may be disjoint. For example, if a large wire-bond die is placed on top of a much smaller flip-chip, and to balance out a spacer of equal height as that of the flip-chip is placed adjacent to it, the die stack will show a sub-stack. Additional Changes ■ Wire bond add remembers certain settings for the duration of the tool session. This includes the wire/finger adding mode and the bond to rings and other check boxes. ■ Nothing that is present in the global defaults will be saved. Those will always be retrieved from the global defaults at this time. ■ The die text in/out wizard has a Package Pin Name column and the BGA text in/out wizard has a Die Pin Name column. These complement the existing fields which export the pin number for those items today.
