I have a custom key set in PCBENV:

funckey Home replay g5

When I press Home, it plays a script to change grid to 5 mils. If I'm using metric instead. I'd like to run a different script.

Is there a way to test what the units are set to?

pseudocode:

if metric

run metric script

else

run inches script

Thanks for any ideas..

I am trying to get an edited dxf shape into PCB Editor 16.5 but I am having no luck with the dxf import.

The shapes all come in wrong and the fixing holes do not import at all.

So I have imported the dxf into my old copy of Layout Plus and it has worked correctly.

But now I am having troubles importing the .max file into PCB editor! The fixing holes are only coming in as pads once I have does the OrCad translation. There are a number of text files left in the directory which appear to be the component fixing holes but I can not find how to import these fixing holes into the Allegro PCB Editor.

Can anyone help?

Hey, I have a quick question about exporting a design to .dxf. 

I have a rectangular board outline defined by a rectangle with line width 0.  It looks like perhaps the board outline is not being generated as part of the .dxf because of this?  Is there a way to get around this?

Hello,

Is it possible to have multiple 'Orcad Property Names' linked to the same 'Table Property Name' when configuring a database. Please see the picture here of my current database configuration (https://www.dropbox.com/s/neq6k5j6wpfo87k/Capture.JPG?dl=0) . My current configuration has the Manufactures name linked to 'Value'. This is a bit annoying because the schematic symbols by default displays the 'Value' field, which is linked to the Manf Name. I would prefer that the symbols display the MPN instead by default. Can I have line 9 in the attached picture linked to two 'Orcad Property Names' (ie...MPN and Value)? I have tried using commas, semicolons, colons, slashes but nothing seems to work here.

Hello all, I am using the demo version of PCB editor v16.3 and I am a new user of this software (I am a student working on a school project). What I am trying to do is to have 2 conductor shapes on the top and bottom layers connected through a via. I do not wish to have any pads, I simply want a hole to be drilled and plated so that the 2 top and bottom conductors are electrically connected. For this purpose, I defined a via padstack with pads smaller than the hole diameter. Now when I insert the via in the layout, I get the following result

where the top conductor shape (green) has been correctly carved out in a circle with diameter corresponding to the via hole.

Now my question is, why is the bottom conductor shape (yellow) not carved out in the same way? I did define my via as a Through type. Does it mean that my via is not correctly defined? What should I do to ensure that I really do have a through via there?

Thank you,

Simon

Hey guys,

I'm attempting to automate the package/STEP file mapping process. I do not see any allegro or SKILL commands that will allow me to feed in a STEP file and a footprint name and map the two. Is there any way to accomplish this? How do people deal with mapping 100+ parts to STEP files right no? 

Hi ,

I am presently working on i.mx6 sololite processor based project which is having 0.5 mm pitch.hence bga breakout is maintained as 3mil tracewidth and 3.33 spacing.

i'll be very much thankful, if anybody can suggest a Fabrication House for this application in India, its getting critical at the moment.

Thanks.

Hello,

I'll try to be concise, I am currently trying to create a sub-circuit in OrCAD.

I created a model on Model editor.
I created a symbol on Orcard.
I associated my model with my symbol by using model import Wizard.
I associated symbol pins with my model terminal.
I included my library in configuration file.

Now i can use my sub-circuit in my project, nevertheless i can't connect pins of my sub-circuit symbol with wires and i dont understand why... (Wire passes through my pin symbol, there is no connection)

Futhermore i got a cache update error when i edit my sub-circuit : "CAP00027 : Design update failed while updating 'name of my sub-circuit' in library C:\CADENCE\SPB_16.3\TOOLS\PSPICE\'name of my sub_circuit'.OLB.  Object not Found

I check the path way, my file.OLB is at the correct place.

I'm completely blocked, thank you in advance for helping.

I am using Delay Tune to do some length matching on some traces and I was wondering if there is a way to see the length while I am actively tuning a trace?  Right now, I have to guess at the length, end the Delay Tune command, check the length and if it isn't correct/adjustable to the way I want it, then I have to 'undo' and try again.

Thanks.

Hi,

I am trying to plot the power dissipated in a resistor vs the resistance (parameter sweep) in Orcad. In case the power source were DC with an internal resistance, I would have got a graph which has a peak at a particular load resistance which matches the internal resistance of the source. A DC sweep with resistance as the parameter should yield me the required result. However, in my case the source is an AC signal with an impedance. I am trying to see at what value of load resistance, the power peaks. I tried using Transient analysis with a parametric sweep on the load resistance, however, the X-Axis is still time. I am trying to see, if I can plot an Average Power Vs Resistance graph to find the maximum power point. Please let me know if such a functionality is possible in Orcad and if yes, kindly suggest the steps to be followed.

Thank you.

I have a rectangular board outline with the 4 corners arc,ed. I need to move the vertical straight segments out a few MM.

When I select SHAPE/SELECT SHAPE  select the outline and try to move a straight segment I get the following error: W- (SPMHGE-609): Arc segment editing not supported.

Is there any way to easily get around this ?

As a common practice in OrCAD PCB Editor, I create the unplated hole by putting a small pad that is smaller than the drill size, so it will be drilled away.  The problem is, the DFM checking software from PCB companies always complains about that and cause a lot of time wasted in communication.  Is there a way to create an unplated hole without any pad on it?

Thanks.

Hi All,

I'm getting some designs that they are requesting to have clean voids around vias/TH pins for certain diff pairs.

I see that in global dynamic shape parameter under void controls tab there is a way to create in-line voids. 

I would like to have similar voids, but to only specific vias/TH instead of entire board.  (Cuts out too much PWR/GND planes)

Has anyone come up with easy solution for this?

I've created via with specific anti etch, but the orientation of the vias needs to be adjusted and I would like to make it pretty fool proof.

Please let me know if anyone has any suggestions.

Is there a way to assign the scroll wheel to zoom in and out?

Is there a way to assign a key to the "AutoConnect two Points" command?

I'm routing a board with 576 diff pairs and every time I click to place a vertex I get an audible "ding". I have tried turning off all analysis modes and that doesn't seem to help. It doesn't do it if I route a control signal so it has something to do with diff pairs checking. It is getting very annoying.

 I just updated to the latest hotfix. Don't recall Allegro doing this before. What is up with that?

Anyone know which cad software a .gen ascii file came from? What other software can open and view this data besides wordpad, notepad.

Looking at the ascii file the first 2 lines are below. Its looks like stencil and some placement data.

Thank you for the help.

When you add  or move something how can you get the program to move the object off grid. ? For example I take a shape and try to move a line segment it moved increments of the current grid. Is there any way to turn off the snap to grid ?
