Hello, i'm a student studying Allegro and want to know about auto-routing function.

When the tool routes automatically, is this function grid-based?

If so, how much is the grid size set to this function?

Thank you.

Mounting hole with vias to ground

$

I have been trying to design a mounting hole with vias around it which short the pin to GND. 

So far, I've created a padstack of the main mounting hole and a via as a Thru-Pin element. I want to add the vias around the mounting holes but I've been getting DRC errors.

The final footprint is being created as a Package Symbol. How can I fix it?

Newbie question here :

I get way too much warnings about "Possible pin type conflict GND".

Many tied to IC GND power Type pin.

In the ERC Matrix, Power to Power shouldn't report any warnings...

How to add solder mask to teardrops ?

Hey guys , when i was making a keyboard pcb ,  i found this images.

 

this is a pcb of keyboard too . what interested  me is that all of it's clines , thr-pins , vias and teardrops are added solder masks , and shows out an open-windowed , blackgold effect , and i think i want this visual effects too .

then i tried it in allegro . first i export a sub_drawing file out of the pcb , selecting the clines and vias before picking the origin spot , and  a .clp file is there in the folder where the pcb .brd file is . Then i open the clp file with the vscode , and replaced all of the "etch/top" and "etch/bottom" with ''Board_geometry/soldermask_top'' and ''Board_geometry/soldermask_bottom '' . then , i import the modified clp file into the pcb , and this help to add a mask layer to the clines and vias . in the 3d viewer it is like this 

it shows the same effect in the first image i posed , the clines , vias are added soldermask .

but i can not achieved the effect in the second image , cause i don't know how to add soldermask to the teardrops . when i exported the subdrawing file , i can only select the clines vias pins but not the teardrop . 

Anybody knows know to add soldermask to the teardrops can give me some ideas ?

I am using OrCAD PCB Professional and recently update with the hotfix. With the latest hotfix installed I am facing issues in selecting OK tabs under setup - user preferences.

I cannot update any .pad path, .psm path, or any features selected under User preferences as I am unable to hit on the OK button.

I tried varying screen resolution yet the issue remains the same.

Any help would be appreciated.

Previously, there was a way to disable the startpage by adding

[Start Page]

EnableStartPage=False

in the file spinfo.ini but in spite of this the start page is displayed in HF007. Any other way to disable it now?

Hi,

I try to use EPC PSpice (.net) model (epc-co.com/.../EPC2035_V2_PSPICE.net) to my simple circuit. After saving the .net file to .txt then .lib, getting .olb file from model editor, adding the .lib file to Configuration Files/Library. The following problem appears during runtime. I tried to break longer lines in the .lib file (in fact no one line is too long) with +, and also tried to use \ at the end of line in stead of + at the beginning based on some suggestions. The problem is always there.

how to copy or duplicate a schematic page?

Hi,

In my design I have a schematic page that I'd like to use as a basis for another page in the same design. In the manuals I cannot find a description of how to get two copies of this page in the design. I have poked around in the tool and can't a way either.

I am using allegro design entry hdl.

Thank you.

Just switched from OrCad ver 16 to Cadence/OrCad ver 17

$

Long time user of OrCad  capture and layout ending with ver 16.2.  Now I have the ver 17.2  Capture and Allegro PCB.  Really not intuitive so could someone point me to the proper user manual to cover copper pour/fill  details.  I translated my layout  .max file and the bottom plane is a combination route and ground plane created with a pour/fill.  After translation I see only the routes  and would like to see everything, which would include the pour.

Does a Tutorial, like that found in ver 16.2, exist?  The 16.2 Tutorial was a very nice reference.

Please do not criticize my verbal use of 'fill', intermixed with 'pour', as I also have to work with PADs and it causes me confusion.

Looking forward to a reply.

Thank you.

Has anyone seen copper artwork successfully imported in Creo Parametric? I've seen it done in a Youtube video, so I know it's possible. I've created an .eda file using Creo View, but all we were able to import is vias. We do have the ECAD/MCAD collaboration license.

Some pages of Allegro PCB 17.2 is freeze under Win10 2020.

My computer was updated by Microsoft automatically last week. Before Win10 2020 was updtated , Allegro PCB was run normally. After updating, some errors was appeared.For example, The Define Grid page of Design Parameter Editor is freeze when i will want to modify Grid data value under the  circumstances which clicked Design Parameter Editor in Setup menu and clicked Setup Grids to modify grid value. In other words, when i clicked Setup menu of allegro PCB and clicked Design Parameter Editor item, in the page, i tried to modify grids value of Setup Grids page, i will get nothing on the Setup Grids page Setup Grids page will be freezed. And i can not close the  Setup Grids page as well as other pages. 

By contrast, if i clicked Grids item of Setup Menu of Allegro PCB , the software will run with no errors as well as modify the grid value sucessfully. 

The Second  phenomenon, the Setup text size page of Design Parameter Editor item in Setup menu was clicked and i can not be modified any value too. The cause is as same as  Setup Grids page. The allegro PCB was freeze too. 

Who know how to solve it? My Computer os is Win10 2020.

OrCAD EDM vault and key requirements for a team

$
0
0

We are a team of five working a complex project. To keep data integrity and the version control we are moving to EDM but, we are in an unclear mode regarding how many licenses would we need.

So for the team of 5, whether we need 5 OrCAD EDM key license and 1 OrCAD EDM Vault or 4 OrCAD EDM Key and 1 OrCAD EDM Vault.

It would be more useful if you can add more info on how EDM vault and Key work combined.

DRC checks for covers

$

Most of our designs are RF and we require channelized metal cover for isolation. More than once we've had via shorting issues due to either overlooking it or last minute changes. I'd like to be able to setup constraints for a DXF layer that represents the cover to any copper that's hot (any net other than ground/return). Is this possible? I'm using Cadence 17.2 PCB Designer. No other add-ons
Thanks

TCL - Get the Most Recent Part

$
0
0

I'm using the PlaceNew tcl procedure OrCAD Capture to have the user place a new part. I would like to be able to get the part instance that was most recently placed on the page and can't find a very good way to do this.

The best solution I have so far is getting the most recent mouse click and selecting a small box at that point and choosing the first object there but this is not ideal.

I thought I might be able to iterate through all parts on a page but the last part in the iterator does not seem to be the most recent part. Also sorting parts by ID or name doesn't seem to guarantee chronological order either. 

Has anyone seen a way to do this?

Thanks
