allegro:can not select unplaced component

$

0

I have a PCB file(.brd) and Schematic(.pdf) from our supplier. Now,I draw the Schematic in Orcad,the footprint of the part is from PCB file. Now,something happend. what i did is as follows.

1. I export the package from pcb file.

2. Draw the Schematic in Orcad.the footprint of the part is from pcb file

3.Create netlist in Orcad.

4. open the pcb file(.brd) in allegro pcb editor

5. inport the netlist.

 Now,after inporting the netlist of the Schematic, I find all components can not be placed. I want to know what is the reason, How I solve it. Thank you

                                                                   


IPC-7351 Level C

Hi all,

Has anyone experienced on using of IPC-7351 level C footprints? Presently I'm using it in one of our project which is a very dense and space constraint board. My concern is,

  1. Is there anything issues we have to take a special care, as to avoid any DFA/DFM?
  2. What is the minimum space we have to keep for two level C footprints (major's and passive's) to avoid any assembly and manufacturing issues?

Any input will be appreciated.

Thanks,

Shiva.

Keepouts

$
0

I have a connector symbol that has two mounting holes. I want to have an area around the mounting holes where there can be no other components. On the bottom side there shall be no traces, but traces are allowed on the top side.

I have tried many different keepouts and the only errors I ever get are for vias or traces inside the keepout area. I can put a component in there and don't get any error.

I have tried:place outline, Route Keepout, Package keepout, all will allow me to place a part within the keepout area.

Suggestions?

Installation Procedure for OrCAD 16.3?

Hi.

 Any one help to install the OrCAD 16.3?

Have to add all Libraries each time.

$

I generally add all the available Library all the time so it is easy search parts amoung them. When I was using OrCAD Capture Version 16.0, when I once add all the libraries, Capture use to remember and show it that way whenever I start the Capture, but now in OrCAD capture version 16.5 SPB it looses that information (libraries that are added in the workspace) everytime I restart the Capture. Is there some setting somewhere that I can enable that'll allow it to remember that. Could anyone help?

NC Drill Problem

$
0
0

I've recently completed a design on a new PCB and I've done two things I haven't done so far with PCB Designer.  The first was to mount a component at an odd angle (13 degrees).  This worked well.  This component also has two non plated slots for alignment pins on the component.  I created the non-plated slots using Pad Designer and incorporated the slots into my package symbol as a mechanical element.  Here's where I'm running into a problem -

 I can see the slots on the board when looking at it in PCB Designer 16.5.  I can toggle the holes on and off on the screen, and the slots even show up on the 3D view of the PCB.  The slots and their respective symbol show up on the Drill Legend and they are included in the hole count, but, when I generate the NC Drill file, the slots aren't showing up.  I missed it at first, but the PCB fabricator sent me an email and wanted to know what to do with the oval-shaped spots in the solder mask, because there was no NC Drill data for that area.  Sure enough, I opened up the drill data using Pentalogix Viewmate, and the slots are not there.   The board fab place is going to manually put the slots in for my prototypes, so I'm OK for right now, but for production boards, I'm going to need this data to be present.

 I'm probably missing some setting in the drill parameters or something, but I have no idea what it is.  Has anybody else run into this?  Does anybody have any idea what I'm doing wrong?  I've tried changing a few settings in the NC Parameters, but so far, nothing I've tried has worked.

Off Grid (Misaligned) components and circuits in Capture.

I've imported a project made by OrCAD Capture 16.0 into OrCAD Capture 16.5 SPB, and all the components and wires have become misalligned to the grid. Thus it doesn't allow me to connect new components to the same. 

In my search here I found this link in this forum: http://www.cadence.com/Community/forums/p/11756/15426.aspx#15426

which mentions similar issue but the solution given needs lots of rework for me as different group of circuits are misaligned by different distance.  

Is there a way to solve this in a more simpler way?

How to reuse the hierarchical block?

$

Hello, everyone.

I am now learning the CAPTURE's complex hierarchical design structure and I am using the software version 9.1. I am now encoutering a confusing problem. My problem is same as the author of the theme:http://www.chronology.com/forums/ShowPost.aspx?PostID=23229

  That is I want to reuse the descend schematic of a hierarchical block(suppose named A) many times, because there are many similar circuit blocks in my design. Firstly I creat a hierarchical block named A and complete the descend shematic of it. But when I make a copy of the hierarchical block A, I find that the reference designator of all the components in the descend schematic are the same between the copy and A. And when I change the componet reference in the descend schematic of either A or the copy, the other change at the same time. This makes the problem that A and its copy refers to the same circuit block but not two similiar one.
  I have read the help files of the software very clearly, but can't get the answer.
Wishing for your reply.Thank you.

OrCAD Capture 16.3 hangs on load

$

My OrCAD Capture 16.3 just quit working. When I load the program, I first see the version and copyright splash screen in the center of my primary monitor. Less than one second later, The main window begins to appear on my secondary monitor. With no delay, and perhaps before the main window appears, one of my dual core processor cores goes to 100% CPU usage (overall 50% CPU usage) and stays there. Meanwhile, the main window, which was only title bar and frame with old graphics still in the middle, repaints with all white and stays all white. A small "Footprint Viewer" window also appears with all white body.

During all of this, if I move the task manager around on the two white windows, they do repaint. At least, their frames do. One couldn't tell if the white repaints. However, the splash screen on the other monitor is still up, and it does NOT repaint as I move the task manager across the face of it.

*Immediately* prior to this problem, I was running OrCAD Capture CIS, which I had run many times since it was installed over a month ago. I tried to generate a netlist, and got an error about invalid characters in the path. I closed the current project, and tried to rename the folder tree containing the project. Windows Explorer couldn't rename because some file in the tree was locked by some program. I believe OrCAD PCB Editor was also running. I closed both OrCAD programs and tried to rename again. I still couldn't rename. I decided to leave the folder names as they were, and created a new folder with a short name and no special chars. Then, I loaded OrCAD Capture again and had this problem.

OrCAD Capture should NOT be automatically opening my project or anything, and I did NOT in the end rename anything. Therefore, my actions shouldn't have led to a condition causing this hang. The closest connection at all is the MRU (most recently used list). But since I didn't actually rename anything, that shouldn't be a cause, either.

I have no clue why the program suddenly started doing this.

Note that when I cancel it by either clicking on the red X in the top right corner, or cancelling it with the task manager, it does take a few seconds but otherwise cancels willingly. It's not like some other programs when they hang, where you get the question about the task not ending and cancelling it now.

Also, two line items appear in the Applications tab of the task manager, both for OrCAD Capture with status "Not Responding".

Any and all reasonable advice on this is greatly appreciated. Note that I have tried rebooting and loading with no other programs working. I have not yet tried to reinstall.

I came across a tool within Allegro a while ago that illustrated the use of a command that allowed a user to draw a series of contiguous lines (not Clines) with a uniform spacing.  I can't seem to find this tool again.  Can anyone point me in the right direction?

OrCAD PCB Editor 16.6 Error

I was just curious if anybody has run into this yet.  I installed the 16.6 upgrade last week, and it seemed to work just fine.  This morning, when I tried to double-click a board (.brd) file to make some edits, I got an error message that says "The program can't start because cdn_xerces-c_2_7.dll is missing from your computer.  Try reinstalling the program to fix this problem."  But, if I open up OrCAD PCB Editor and then click "File" and "Open" and then browse to the file it will open it that way. It didn't do this to me last week when I first installed the upgrade.  Right now, all of my existing board files were generated using the previous 16.5 version of software.

 Has anybody else had this problem?
