In this analysis,when i try to export the specific net using signal explorer, default of ground is getting extracted on the signal explorer. Otherwise the when i try to select  small single net, whole entire circuit is been get extracted.

I have created the memory circuit as a module from 8 Layer Stack-up and i want to reuse the module in the 2 Layer Stack-up as well as i need to follow the Refdes sequences as per my current design. While bringing the module to the current design the tool ask me to provide prefix for the entire circuit( for Ex. *_U1,etc...) and i cannot be able to rename the Refdes. Can any one of you explain me the procedure to rename the module Refdes.

Is there a listing anywhere of the stock footprints and the names Orcad uses for them?

For example, I have a 0464001.DR Littlefuse UMF, and don't know if there's a footprint already.

why can't I remove the fixed property of a symbol?

Foot print conversion from .LLB to .BRD?

Hi..

I need to convert some footprints from .llb to .brd directly.I had tried  option in layout tool-----> Catalog---->Create----> .... that conversion i is only possible in the OrCAD Layout 16.2. I had also succeeded in that.

Then now using Cadence 16.6.038. The  above option for conversion is also known, but me need to import .llb files directly to pcb editor. It is possible.

Most of old product  libraries are in older product. I had imported the max files and worked with it.

Either any tricks for conversion of libraries into PCB Editor. I want to use lib files directly in PCB editor.


IC trace length calculation

Hello,

how I can calculate the IC trace length (or better package delay) of any IC using only IBIS model? I need this data to match relative delay of nets in target PCB design.

I think I need to make any simulations to calculate this kind of delay.
Could someone provide to me any instuctions how I can implement this or maybe provide example, please.
Hope for you assistance.

(Is this the right place for an Orcad Capture post?)

I have a schematic from a previous project that has enough elements in common to a new one, that I am editing the previous schematic. How can I make the new project have a NEW (current) create date in the titleblock rather than retaining the date from the previous project?

How to compare two Schematic Capture Projects

Hi all,

I am using OrCAD 16.6. I have two designs that I can't track the changes between them. I am wondering if there is a way to compare and find differences between these two designs? Afterwards, I am going to do the same for their PCB design files - .brd files -


Comments are welcome

Hi all, a question about inserting a section.

I would like to insert a section between two sections of an existing heterogenous part.

e.g, insert a section U?B between two existing sections U?A and U?B.

how shall I go with this? Currently I change the number of section in the Option but the new section will only append at the end of the part.

Thanks in advance.

I am trying to support some old software here at my company while transitioning to Cadence 16.6.

My license file supports older long term lease OrCad Layout Plus and Layout EE licenses.

I need to know the differences between these two packages.

Can someone give me a short list of differences?

Thanks so much.

Hi..

I had finished my board and finally drill chart is also been get generated. Then my doubt is in OrCAD layout, drill file will been get enabled drill chart table below, but in the OrCAD PCB editor the when i try to import it on GC PREVUE 22.6, the drill holes are only get enabled. The below drill  table are not get enabled.

I had tried to import the layout drill file and PCB editor drill file separately. I had find the drill chart table below the drill layer on layout. But i can't find out the drill table below the (.drl) PCB editor file.

 The comparison image link below. See the image attached.

Allegro Design Publisher

I'm looking for some feedback in regards to Allegro Design Publisher.

All I am really looking for is a way to print intelligent pdfs from Allegro. I want to print all layers at once and have the ability to turn them on/off in the pdf. It makes it easier to review for folks that do not have Allegro installed or do not want to bother with the free viewer.

AutoCAD has this function.

Are there any other features that you've found very useful with this add-on? 

Thanks

Dimension fixed can not be deleted

I have a BRD file that was converted from 16.2 to 16.5.  It has a leader line that was fixed in 16.2.  I am unable to delete it in 16.5.  Is there some way to change the property on this dimension?

Licensing Question

$

We have a flex license for two Allegro PCB Design seats. While we renew and pay an annual maintenance fee on both licenses, if it happens that one is under utilized and we only use it sporadically, I like to understand what happens if we pay for maintenance on only one seat. Will the second one stop operating when the maintenance expires? Is there anything that is going to bar us from using the second package? We paid for both packages, just don't wish to maintain both of them, does the second one become inoperable?

I am not clear on where to find these answers. If anyone has an explanation or a link to an explanation that they can share, this would be greatly appreciated.

I am trying to place the Offpage on a schematic page through Placeoffpage command

i.e PlaceOffPage(x, y, libName, symbolName, OffPageName)

Command i am writing is PlaceOffPage 3.0 4.0 D:/proj/lib/Inductors/olb/INDUCTOR.OLB VCC MyOffPage

I am getting the following error message : ERROR(ORCAP-1687): Macro Player. unable to place object.

In command window I get : Command Failed. Reason: Invalid Path or Invalid Argument(s).

I've tried different path formats but it doesn't work for me. 

Any solution to this problem?

diff pair : change a routed pair space due to constraint change

Hello,


Due to change in my PCB stackup, I'd like to change quickly a lot of differential pairs since the space between the pairs has been modified.

Is there a way to do it very quickly rather than sliding each etch segment one by one.


Thanks
