OrCAD Capture 16.3 hangs on load

$
0
0
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 was having cadence 16.3 in my PC Before for some instance i installed 16.5 also in my pc without uninstalling the 16.3.Now i am getting error message if i tried to open 16.3is attached below..........Somebody please help me.

Text in PCB Designer 16.5

$
0
0

I'm starting to get more familiar with Allegro's PCB Designer, but I'm still quite confused about the way text is handled.

 

Looking at one particular example: 

In OrCAD Layout 10, I had silkscreen text built in to my footprints.  This text had a certain height and line width and when I placed the part in Layout, I could position the text appropriately.  When generating artwork, it was treated just like any other object on the silkscreen layer and this all worked great.

 

Moving into OrCAD PCB Designer 16.5, my footprints also have text reference designators on the silkscreen layer.  They all use a default text block 2 (width 23, height 31, line space 39, photo width 0, char space 8).  Suppose want to use 8 mil width on all of this text.  How can I see what that would look like so I can move text around appropriately?  Once I have my text positioned correctly and I'm ready to generate artwork, how do I get the text to show up?  Currently, even though I have my "Undefined line width" set to 8.0 for the silkscreen film, no text will show up in my gerbers...  What am I missing here?

 

I get the impression that the Allegro method of handling text is supposed to be powerful, but I'm just not understanding how it's intended to be used.

Padstack replace not working in package designer OrCAD PCB 16.6

$

Hello folks,

For some reason, I cannot replace my padstack in an existing package design.  I am using OrCAD PCB Editor 16.6 S012.

Here is what I do:

1. Open the symbol package design (.dra).  Pins are checked in the find window.

2. I click Tools -> Padstack -> Replace, click on the pin I want to replace and the existing padstack name appears in the Old Padstack field of the options window.

3. I then find the new name in the new pulldown menu.

4. I then option-click  in the design window and click Done.

When I hover over the padstack I wanted to replace, the  padstack is still the old name. There was no error message indicated.

The new padstack does exist, is valid, and it is located in the path.  I can add new pins using the new padstack but I cannot replace existing pins.

Has anyone run into this before?

Thanks in advance,

Allan

Updating Part (Schematic Symbol) in Design Entry HDL

Hi,

I'm using Project Manager - Design Entry HDL in creating schematic diagram.  I placed a diode symbol in the schematic diagram.  After awhile, the diode symbol was modified (Pack_Type was added in the properties) in the PCB Librarian - Part Developer.  How can I update the diode symbol in my schematic diagram?  Is there a way to update all the diode symbol at the same time?

Thanks,

Mabel


Design Lock in HDL / Read-only Design

Hi,

I would like to ask how to make the schematic design a read-only file.  All previously created schematic designs will be uploaded in the server.  These designs can be used by other design engineers for their projects.  Engineers can reuse the existing designs (blocks) but are not allowed to modify or change the circuit of the existing design.

How should this be done?

Thanks in advance!

ODB vs Gerber Layer naming conventions and Drill Figure matching

$

I have been sending board houses and Contract Manufactures both Gerber and ODB++ files, since not all of them can read ODB++.  I am now in the process of making Artwork Layers, X-section and ODB match.  This includes Drill Chart Figures and drill order.  Unfortunatly Allegro Version 16.5 only allows me sequence "Plated first" or "Non-plated first" in Ascending or Decending order.  Is there a way to sort Ascending by drill size only?

 Thanks,

Hello - Yesterday I attended a Mentor Graphics presentation on ODB++.  Naturally, the presentation was MG slanted but during the presentation they mentioned "ODB++ Inside" for Cadence products.  I'm interested in any comments on this tool/feature in particular and the Cadence migration toward ODB++ output in general.  Thanks in advance.

Change the grid size while routing in Allegro with a hotkey, Keep routing at the same time

$
0
0

When routing a design more often than not I change the grid when routing.

I created a hotkey to do this and indeed the grid does change but when the hotkey executes I loose the cline segment I had picked.

here is the macro

funckey 1 "define grid;etchedit;setwindow form.grid;FORM grid non_etch non_etch_x_grids 100;FORM grid non_etch non_etch_y_grids 100;FORM grid all_etch all_etch_x_grids 100;FORM grid all_etch all_etch_y_grids 100;FORM grid done"

If I am routing in a trace I can go up to the tool bar and change the grid spacing for all the etch and click ok in that dialog. The grid spacing changes and I dont loose my picked trace so I can keep on routing with the new grid settings.

Does anyone know how to create a macro to do this. It would be a time saver...I just want to be able to change the grid in an easy way while routing at the same time ... lol :) without having to select a menu to do it.

Thanks Scott.

Hi, when i edit the dynamic copper,it didn't avoid with other cline segments,i tried some ways as follows: 1.status-shape ,update to smooth 2.move the shape outside of board and then move in 3.edit shape --raise priority. it didn't work. the only way i can do is to manual void where the shape couldn't avoid. anyone has a better solution ? thanks!

rpc server not available

Hello, all.

I have installed the Cadence 16.3. and it worked well.

Several days later I launched Visual studio 2008 and came the problem. In capture, I want to put two VSTIM in SOURCSTM library. When I use the option " edit-pspice stimulus ", it gave me the message that "Only one instance of the Stimulus Editor is allowed to run. Please close the other instance before starting another one.". and if I want close the capture, it gave me another message:" rpc sever is not available."

I am not good at computer, so hope you can give more detailed things. 

Since I am not from english speaking country, hope you can understand and I would appreciate any help from you.
