12/26/2023 0 Comments Cadence allegro 16.6-s032![]() I would have preferred it if Cadence just admitted that hierarchical designs are not supported, so that I would not have gone down the path of a complex hierarchical design. CoDesign Allegro BRD APD / SiP APD / SiP Cadence Allegro BRD. This is a severe disappointment, and has set our project back by months. Please somebody prove me wrong here, as I'm in the process of undoing 2 months of work on an incredibly complex hierarchical design, to flatten the design, BEFORE we can even start working the layout. t (00:00:24) paddesigner 16.6 S032 (v16-6-112CK) Linux I32. For this reason, and as of, I do not think that the Cadence software actually supports maintainable and robust complex hierarchical circuit board design. This deletes any correlation to the physical circuit that you have already laid out on the board. ![]() From what I can tell, any time you cut and paste a hierarchical block (to move within a schematic page or move to another page, for example), the OCCURRENCE properties (your actual reference designators used during layout) are DELETED and overwritten by a random new reference designator or question mark (depends on the annotation checkbox), and all parts in the hierarchical block are assigned new ID values. WARNING! If you netlist a complex hierarchical schematic and layout a PCB, you will be unable to make changes to the schematic after the fact. Cadence Allegro PCB Symphony Team Design Option supports collaborative placement, routing, auto-interactive routing, interactive routing, and shape design to let your team dedicate their time and efforts to get designs done faster through real-time concurrent design collaboration. The only way is to change the reference designator manually in property editor view. I had some problems also manually change the reference designator in sub-circuits by double click text to open the display properties dialog, changes made in one occurrence affects other occurrences and other weird things. The Overflow Blog Turns out the Great Resignation goes both ways (Ep. Browse other questions tagged schematics routing cadence allegro or ask your own question. If I copy a hierarchical block, the reference designator does not change automatically, and I want that it does. As of version 16.6, there is a 'Slide Etch' option as well, although I havent played with it yet. I'm asking this because maybe I misunderstand and / or I forgot to set something This ensures that each occurrence gets a unique reference designator."ġ)sub-circuit reference designators change automatically at each hierarchical block placement/copy actionĢ)user have to change sub-circuit reference designators at each hierarchical block placement/copy action Therefore, for a complex hierarchical design, the preferred mode of annotation is Occurrence. For this, the yellow columns for the parts must have unique reference designator. HOW I can load the new netlist file (created from new schematic with few (10) components added) to the original PCB file directly and modify from this original PCB file ?Ģ."Note: As a part will have more than one occurrence in a complex hierarchical design, it is essential that all these occurrences have a unique reference designator in the design. I decide to modify this schematic by adding about 10 components to this schematic and make a new PCB (from the original PCB downloaded) for my own application. 1943899 ALLEGROEDITOR SHAPE Only one Shape to Route Keep In DRC in release 17.2-2016 compared to two in release 16.6 2 R t1 ( E' m X5 H6 q, \ 1944041 ALLEGROEDITOR SHAPE shaperkiautoclip makes shape voiding incorrect / f. files) from the original PCB, I have exported the library ( Edit -> Export -> library) from this one.ġ. Hello all, I got a schematic and a PCB (.pcb) board using Allegro Cadence 16.6 from Internet. 1845011 ALLEGROEDITOR DRCCONSTR When upgrading from 16.6 to 17.2, Spacing constraints for shape to mechanical.

Community Forums PCB Design PCB Design Allegro 16.6 snap to cline. Now I finished my schema and generate a netlist file and loading to a new PCB file after drawing a Bounding board outline (as standard method). I don't touch/change any net names on the original schematic, just adding and few components removed (not much) from this schematic. I decide to modify this schematic by adding about 10 components to this schematic and make a new PCB (from the original PCB downloaded) for my own application.
