Orcad pin ignore missing in latest version.

$

0

In previous versions you could generate ,for example , an op amp with 4 sections. Each section had the same power and ground pins. They you could go into the pins spreadsheet and select pins you wanted ignored(not displayed in the schematic), That way you only had power and ground showing on one section. With this never version of the symbol editor I cannot figure out how to do that ? Any ideas.


can orcad tcl script handle things like changing symbols in libraries?

my question is how to fix the issue when importing DXF using cadence 17.2 . the DXF is ok for cadence 16.5.   the issue is logged as following:

What layers and files are used to produce a Milling file?

I am using Cadence 17.2 and the layer I used before for producing a Milling file appears to have changed.

Can anyone tell me what files are needed or which layer is used to define the Milling!

Symmetrical stackup = asymmetrical impedance?

$
0
0

Hello all together,

I'm trying to design my very first flex PCB with impedance 50 Ohm single ended and 100 Ohm differencial signals.

I have some problems to understand the calculation from Cadence in the stackup.

Its a three layer stackup and reference plane is GND in the middle.

From GND to TOP and BUTTON its symmetrical so I'm expecting equal impedance on both outer layers.
But Cadence seems to have another calculation.

What do I miss in this situation?

And as far as I understand Cadence only know single ended impedance.
So assuming a VERY large gap between two differential pairs each 50 Ohm impedance add together to 100 Ohm differencial.
So there is no way to get a correct impedance for parallel routed differencial pairs directly in Cadence from the contraint manager, right?

Thank you very much!

hello

i have a shape that is not connected to any object but have a net assigned since i copied it from some other shape.

how can i remove the net from the shape?

i simply want the shape as a dummy net

If this is not possible, how can i copy a shape without retaining the net?

Whenever i copy a shape, the net comes with it.

importing logic introduced lots of drc errors related to max/min neck length

Hi, 
is there any way to create a 3D shaped board (not planar) using OrCAD? If not, what is the best way to handle such design? 
I'm looking for alternatives to MECADTRON Nextra on the market. 

Thanks a lot for your ideas.

When I am in 3d canvas view I will try to export a step file. However; in the 3d canvas mode when I try to export out a step file the system will get to some percentage of export and then lock my pc up.

If I am not in 3d view I can go file>export>step, I am able to export out a step file from my database. This step file is much smaller and does not give the mechanical group all the necessary information.

Is 3d canvas not capable of exporting a larger database.

Veresion Control in OrCAD schematic and PCB

Hi,

I recently moved from altium to OrCAD PCB. Our projects rely on previous versions of our desings and will be slightly modified to create a new product. In altium we had a version control feature, which when enabled, the tool will automatically save the modified design as a different revision. I did not find this feature in OrCAD. This is a very critical feature for me.

Is there anyway we can do the automatic version control in OrCAD?(rather than doing "save as", which is not a reliable solution)

Kindly help me on this issue.

Hybrid library vs normal one

$

We use Orcad and we want to update our libraries. When we place a part and want to rotate it,we don't like the layout of the names and values and thus have to manually reposition them. It's not a big deal but it gets annoying after a while.

To solve this issue, we came with two solutions:

-Create for one component two parts(an horizontal and a vertical one)

-Create a symbol with the convert option which allows us to choose in a click

Does anyone here have any suggestion on what would be best ? I'm leaning towards the convert option because it seems faster and we have less components, but my supervisor would like to know what people in the industry do. I've linked some images to clarify what I mean. Thank you very much, and even if you don't use Orcad,if you have an informed opinion, I would still like to hear it

How to derive a section of a two-section part to create a new part.

Hello,

I am trying to create a new part from an existing part (existing part consists of 2 parts per package), but I only need section A for my new part.

I tried several ways of deriving the new part by searching for the entire part then selecting and placing only section A in my schematic, then Edit<Derive Database Part, but when I do that, it says "The part with the schematic part number xxx-xxxxx already exists..wuould you like to continue?" I do not want to overwrite the existing part, rather want to create a new one with a new part number and footprint number. How can I do that? Any help with this would be really appreciated.

Hello group,

i am requested to insure that the total thermal relief copper cumulate on all layers will not be greater than a value.

This would be for soldering purpose, to avoid "cold" holes

Any advice how to adress this?
