How to transfer etch/conductor delays from Allegro Package Designer (APD) to pin delays in Allegro PCB Editor

The packaging group has finished their design in Allegro Package Designer (APD) and I want to use the etch/conductor delay information from the mcm file in the board design in Allegro PCB Designer. Is there a method to do this?

This can be done by exporting the etch/conductor data from APD and importing it as PIN_DELAY information into Allegro PCB Editor.

If you are generating a length report for use in Allegro Pin Delay, you should consider changing the APD units to Mils and uncheck the Time Delay Report.

In Allegro Package Designer:

  1. Select File > Export > Board Level Component.
  2. Select HDL for the Output format and select OK.

       3. Choose a padstack for use when generating the component and select OK.

This will create a file, package_pin_delay.rpt, in the component subdirectory of the current working directory. This file will contain the etch/conductor delay information that can be imported into Allegro.

In Allegro PCB Editor:

  1. Make sure that the device you want to import delays to is placed in your board design and is visible.
  2. Select File > Import > Pin delay.
  3. Browse to the component directory and select package_pin_delay.rpt. The browser defaults to look for *.csv files so you will need to change the Files of type to *.* to select the file.
  4. You may be prompted with an error message stating that the component cannot be found and you should select one. If so, select the appropriate component.
  5. Select Import.
  6. Once the import is completed, select Close.

Note: It is important that all non-trace shapes have a VOLTAGE property so they will not be processed by the the 2D field solver. You should run Reports > Net Delay Report in APD prior to generating the board-level component. This will display the net name of each net as it is processed. If you miss a VOLTAGE property on a net, the net name will show in the report processing window, and you will know which net needs the property.

How to transfer custom title block from Orcad Capture to PCB Editor

Hi,

So I was trying to update the title block of a schematic that I have. The title block that was on there was out of date . I clicked on place --> title block and was able to find the title block that I need. I also have a .OLB file that contains that title block. Then I created a Netlist with the old BRD file as the input file (To keep it as is but modify changes) but when I do that I still do not see / cannot place the title block that I need. Under Place --> format symbols in Allegro , I do see a title block that is coming from the database (But it's the old one). I don't know what to do at this point and would appreciate any tips. I did make sure that the path to where the library is , is defined in the user preferences. 
I also tried copying the title block under the library folder in capture before creating my Netlist and that did not work either.

Thank you all.

Purging duplicate vias in pcb editor

How do we purge/remove the duplicated vias in the same location of the PCB editor? These vias are not the one stacked and they are just blind vias running in internal layers 12-14. I find there is an additional copy of the blind via at the same location. Not sure what caused this issue.

Launch footprint editor from Capture or PCB Editor?

I'd like to be able to edit a footprint for a part in my design without needing to find the footprint filepath and directly open that file in PCB Editor. I see that I can view footprints from Capture, and that doing so shows me the footprint path, but I can't find any way to launch the editor. Is there any way to go directly from a part in a Capture schematic or a placed part in a PCB Editor board design to editing that part's footprint?

What's the difference between Cadence PCB Editor and Cadence Allegro?

Are they basically the same thing? I am trying to get as much experience with Allegro since a lot of jobs I am looking at right now are asking for Cadence Allegro experience (I wish they asked for Altium experience...). I currently have access to PCB Editor, but I don't want to commit to learning Editor if Allegro is completely different. Also walmart one, are the Cadence Allegro courses worth it? I won't be paying for it and if it's worth it, I figure I might as well use the opportunity to say I know how to use two complex CAD tools.

PCB Editor SKILL program for finding pin location

Hi,

I wanted to find the location of a pin in the design using skill program. pin_dbids = axlDBGetDesign()->pins, this gives me all the dbids of the pins that are present in my design. But when im entering that dbid, pad = axlDBGetPad("000001EA8FD8B9F8" "package geometry/assembly_top" "regular") it is throwing an error stating "This dbid is not user defined. Please enter the user defined". So please provide me a snippet so that I can get the exact pin location in the design using skill script.
