How to create an assembly drawing in PCB Designer 16.5

November 9, 2012, 6:32 am

Hi everyone,

I was hoping to find some help on how to generate an assembly drawing using version 16.5 of PCB Designer.  I can see under Manufacture -> Variants there is a selection to create an assembly drawing, but when I try to use that function I get an response that says, " Variants file 'variants.lst' not found."

I don't have a variants.lst file because 1) I do not intend on having any variants for this design, and more importantly, 2) I don't know how to create a variants.lst file or the required format of such a file.  It appears I do not have a license for the Allegro Design Entry HDL variant editor, which I would apparently need to create a variants.lst file.

I've also tried turning off all details except for Board Outline, Package Geometry->Assembly, and RefDes->Assembly.  I've got several small parts placed close together, so I'm not sure how I can clearly associate the Ref Des with the part in many cases.

 So, how do I create an assembly drawing?

 Thanks guys.

Many thanks for your help and kind regards,

Our CIP schematic symbols are not showing up.  Just the ones in the supplied library.  Everything works fine in 16.3 but we are trying to get the upgrade done.

I looked for this error and everyone seems to address the issue by changing the artwork type to RS274Xand decimal places to 5.I also run dbdoctor and have 0 errors but when I try to translate I get:    

 

*********** ERROR  12Nov2012.141047.467  5924  91.1 Update 1(38) Windows XPCadence Interface - File geoms_28381155.out has wrong header*********** ERROR INTERNAL 12Nov2012.141047.467  5924  91.1 Update 1(38) Windows XP(ind_list != ((void *)0) && ind_list->magic == 12121212) at D:\vSureSRC\s911\gen\gen_sort.c 1236

  

 

    Why is trying to read something from my D drive? Could this be the cause of it? I´m running the translator from within Allegro menu (file>export>odb++ inside)I´m on Allegro PCB Editor 15.5

Teaming up on a Design

I'm looking for some guidance on the following.  A co-worker and I have teamed up on a fairly intense 12 layer design (controlled impedance, DDR, tuned traces, 684 ball BGA, etc)  My partner is responsible for placement, routing and meeting all of the technical design challenges and I am responsible for cleaning up the design cosmetically (silk placement, fab dwgs, assy dwgs etc) and preparing it for release to fab and assy.  I am aware that there are features within the tool (v 16.5) that enable a team approach to the design (sub-drawings, clip files, etc) but I have very little experience using those features toward this end.  Can anyone clue me in to documentation or tutorials that may be available for accomplishing this?  A sincere thanks in advance for any help you can provide.

Allegro free physical viewer and Windows 7

Hi,

 

I'm running the Allegro free physical viewer on Windows 7 and I see that the screen is not refreshing.

This results in the nets and components not being highlighted when I select them and the names are not popping up (tips) when I hover with the mouse over the layout.

 

Has anyone encountered this problem?

 

Thanks,

Sharon.

How do you array objects in Allegro "Package Symbol" editor ?

I'm a new Cadence Allegro user. I'm making a complex package symbol with over 30,000 shapes. My normal procedure using different CAD tools is to make one pattern then use the "step and repeat" function of the tool to make the array. I provide the quantity of items to array and the step distance. Is there a method in Allegro that allows this type of functionality other than copying the shapes manually?

The end goal is to have a library part with 30,000 shapes and less than 100 "pads" for net connections.

Thanks,

mechanical parts in Capture to BOM

Is it possible to add parts to the schematic that are not part of the PCB design? I have a carrier that has multiple parts (die and single layer capacitors). The schematic symbol visually has all of the components on the carrier but they are just drawn as lines. Is there a way to get all of the carrier components added to the schematic BOM without actually being part of the PCB design?

CIS Spreadsheet - Additional Unwanted Fields

I set up CIS using a spreadsheet with component families organized in separate tabs.

Within CIS some of the component families have a number of undefined fields added to the CIS listing: F9, F10, F11 etc.

Any ideas what is causing this?

I seem to recall a document describing specifics of the spreadsheet requirements but can't locate this. Thought it contained something about defining data ranges as "table" etc. - does anyone know if such a document exists?

Video tutorial for using Allegro Design HDL

Hi friends,

I have been using Allegro capture CIS all these years and having no idea about Design Entry HDL. Hence, for my current project, I have been going through the User guide of DE-HDL but it has some 600+ pages and is time consuming. Request you to suggest some good video tutorials to understand the tool. My tool version is 16.6.

Thanks in advance.

 

Warm regards,

Ideal gates, how?

Using 16.0, I encounter some problems with ideal gates. No problems with real gates (7400.olb, etc.), though. 
I understand that Gates.olb provides ideal gates. A simple NAND is enough, to show that it does not work for me. The simualtion (pspice) fails on all accounts, except of the net aliases of the inputs (digital sources).

I really wonder what my mistake is?
