Migration Guide for Allegro Platform Products Allegro Platform Package Products October 2019 118 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. ■ In addition to the diacompare command to compare die abstract files, 16.6 has a new command dia compare command that brings up the Dia Abstract Compare dialog box (Reports – Die Abstract Compare) that lets you pick the two files to be compared and the options to use (defaults match the default options for the batch tool). ■ The db diary command (Tools – Database Diary) command now has options to show line numbers in the database diary and to delete a range of lines from the history. ■ The purge unplaced comps command lists module instances that have no children (empty) so they can be purged from the design. Modules are identified by adding module after their name to differentiate from objects with similar names. ■ The auto assign net command (Logic – Auto Assign Net) has a new option Exclude pre-routed pins in the Automatic Net Assignment dialog box. When this option is selected, the command removes pins in the source set that are routed to any other pin and removes pins in the destination set that are routed to any pin in the source set. ■ The auto assign pinuse command (Logic – Auto Assign Pin Use) now has a new option Override pin use on selected instance only in the Auto Pin Use Assignment dialog box. When this option is set, only the selected component instance are updated. By default, this is not checked and will update all instances. Checking this enables front- to-back flow with SCM where power/ground pins are assigned to signal nets in the codesign flow. ■ Now you can select a BGA from the BGA list instead selecting from the canvas in the allegro_component command (File – Export – Board Level Component). It now lets you know when you run the command if there are no BGA. ■ The allegro_component command (File – Export – Board Level Component) now has options to set the directory to write to (Library name) and to specify exporting a flat hierarchy (Export flattened hierarchy) where all files are written directly in the specified directory. Hierarchical file structure is the new default. ■ Now you can swap the rotation and location of two pins by choosing the Swap – Placement from the pop-up menu for pins in the Symbol Edit application mode. ■ The net list in command (Generate – Netlist-In Wizard) allows import of nets without specifying any pins to assign them to. In this scenario, the purge nets option is disabled on the final page of the wizard, since it would just result in all the newly imported nets being removed again. Migrating Pre-16.3 Designs With Assembly Rules Checks In the SPB 16.3 release, Constraint Manager tool integrated with SiP products, has been enhanced to support capturing Assembly Design Rule Checks in Constraint Manager.
