Is there a software alternative for OrCAD for Ubuntu or is there any way I can run OrCAD itself on Ubuntu?
Im back again with a question about Orcad, thanks to everyone that tried to help last time, which ended up as a weird glitch. This time Im following a premade example and need to place a multi section footprint. It is a relay where I need to place the contact portion of the symbol on page one and the coil portion on page two. Any help appreciated
Hi Everyone,
I've been doing hardware design for five years now and have recently made the decision to move to a small company where I will be the first and only hardware engineer. My prior employers have had larger (10-20 person) electrical hardware orgs and I've only used OrCAD in these past roles.
As the only EE at this new role, I now have the option of selecting which ECAD system to use. I've heard generally good things about Altium Designer and had the impression that it was a little more suitable for smaller-scoped products/orgs, but looking into it more closely I'm not sure if there is as big a difference and think I may be better off just using OrCAD Pro. Can anyone provide some insight?
Some of the factors I'm considering are:
-
Footprint library. Does Altium come with footprints that people actually use? My only experience has been making these myself/in-house)
-
Part Library Management. I've found OrCAD to be pretty good on this front, especially for a shared library used by the whole org.
-
Layout capability (obviously). This actually will not matter as much as I expected from the get go, since I don't think any of the immediate work will be high-speed or heavily contrained. For this reason I was also looking at DipTrace but am concerned about its performance for larger numbers of nets/component count.
-
Usability as a lone hardware engineer.
EDIT: Thank you so much for all the insights everyone, I really appreciate it! I'm going to look into using KiCAD since the immediate design needs do not appear to be high-complexity (low speed, fairly small component counts and board sizes) but will probably stick with OrCAD if there is a need for higher complexity design work.
I'm creating an OrCAD footprint for the Raspberry Pi Compute Module 4 that I hope to make public in the near future. I'd like it to be as clean & flexible as possible so that other engineers/ hobbyists can easily drag & drop it into their projects. To that end I've run into a bit of a problem.
The CM4 has numerous VCC and GND pins on the same net that I'd like to be defined as unconnected on placement (that is, OrCAD Capture recognizes each pin as being separate rather than automatically connecting like- named pins to an internal net). I foresee projects with very tight mechanical constraints needing to leave some ground pins unconnected & I want to ensure other designers can do this without manually overriding DRC errors.
Tl; DR: How can I define pins with identical names that remain unconnected from one another in schematic capture? Is there a prefix/suffix I can add to the pin names that is not visible in capture?
Thanks in advance!
Today Im started my lessons on OrCAD and am drawing a simple schematic and am having trouble. I would like everything to snap to the grid but can’t seem to find a way for the parts/wires to snap directly to the grid. They’re always floating in between my grid points/intersections.
Im also having a problem just connecting wires. I keep getting floating line/pin errors. The wire tool doesn’t seem to snap to pins of components like Im used to in other programs. It seems like I have to find a sweet spot within the pin’s box for it to connect to the component and even then it seems like luck if it actually connects properly.
Any help appreciated
Hi! A few years ago I decided to download OrCAD, I think it was the student program, I don't remember, but I remember the password so I told myself to download OrCAD again, any version, be it trial. I don't understand one thing, I want to download the program, why do they ask me to register again if I am already logged in? If I try to register, it tells me that my email address is already used, and of course it is already used since I registered a few years ago, and the student program is no longer available for me.
I would also like to download OrCAD version 16.6 if this is possible, no matter if it is trial.
In the end any version of OrCAD is fine, but their platform is very weak.
Hey, first time posting here
So I used Cadence software (OrCAD and PCB editor) all throughout uni and designed many boards with them, and now that I've graduated I wanted to learn KiCAD and try a few projects with it. Unfortunately ever since I installed it, I'm never really able to get a project rolling like I am with OrCAD. I'm not really sure what the hold up is, so I was wondering if any of you made the same switch, and wanted to know if you have any advice for how to get a project rolling? I'm thinking maybe I should try a few step by step tutorials to see where all the menus are and stuff.
Thanks!
How do you change duty cycle in OrCAD? regarding to the simulation file? Can someone with OrCAD knowledge explain to me how I can achieve this?
Excuse the silly question but I am a beginner. I am looking for a a schematic symbol of a 12 pin header for my circuit. Which library can I find it in? Is there a library in OrCAD for connectors?
Thanks
I'm in a bit of a pickle.
I was given .pcb Allegro files to revise (I have Altium Designer) and I don't have a copy of OrCad. Altium stupidly requires an activated copy of Cadance to be installed in order to "decrypt" (or whatever) the .pcb files.
This will be a recurring kind of setup unfortunately so I can't squeak by with the timed trial of OrCad since they discontinued the free/lite version.
Does anyone happen to have a legacy installer for the free/Lite version of OrCad? Thanks so much!
Hi all, I'm looking for a good systems block diagram creator with a hierarchical structure in which I can push in and pop out of blocks. Cadence virtuoso does this beautifully but this is of course an IC design program and way overkill for just system blocks. Orcad has some amount of functionality but it's too 'schematicy' if that makes sense. AFAIK Visio is unable to push in or pop out of blocks, unless someone knows otherwise?
So, I've got a schematic that is for OrCAD, but none of my machines can run it and I primarily use Eagle. Can someone help me out and convert a schematic for me to something that Eagle can read (like ascii accel)?
It's for a Xavier NX carrier board for reference. I don't think I'm allowed to share it with everyone so comment or message me or something.
In Altium, if I want the same hierarchical block 32 times, I can add that block once and then specify "repeat(myblock,1,32)". In the Altium terminology, that is known as a multi-channel design.
Does OrCad have a similar feature, and if so, what is that feature called? Searching for "multichannel design OrCad" or "repeated blocks OrCad" hasn't yield any relevant results, so I figure that I simply don't know the proper term to use.
Hi,
I don't know how to construct a PSpice model of MOSFET that are not included in basic libraries in OrCAD PSpice 17.2.
I found somewhere that MOSFET can be modeled with the template statement
.model MyMOS NMOS (Level= Rg= Rd=5 Rs=1 Vto= Kp= Cgdmax= Cgdmin= Cgs= Cjo= Is= Rb= )
but I have two problems here.
First, some of this parameters cannot be found in datasheet (I assume that they have to be calculated, I don't know how).
Second, I want to build more accurate model of my MOSFET. It looks to me that this parameters won't give you good model. I'm not sure.
Here is the datasheet of one of MOSFETs that I want to model:

Sorry for my bad english.
Thank you!
I had an idea for a circuit and noticed I can't download Lite for my new computer. So now I kind of miss it and feel like I took it for granted :(
Anyways, I'm not a student anymore so I can't really get it.
Hi everyone im on my 3rd year of university and i have a project to design an amplifier that amplifies the vin 100 times in orcad and i cant figure out how to make it amplify i'll post some screenshots of my simulations and design maybe someone can help.
this is my time domain simulation green is the input red is the output
Its a circuit design and simulation software that I have to use for work. I tried to look online and the most recent post was in 2015 about the topic. Has anyone else used this software or has any viable alternative to it for linux ? Thanks
I recently got the Orcad 17.4 Bundle.. every thing seemed fine till I realized orcad does not support artwork printout with drill holes. All other s/w like diptrace etc do that... I came across a vedeo which showed a plugin called nsWare, that had a feature "plotting with drill holes".. I am able to install their PDF print , but none of their other plugins.
help pls..
I use Cadence Orcad/Allegro at work and wanted to share the design resources that I use. So here's a list (feel free to suggest more and I'll add them here):
Hello!
I was wondering if there some accessible good models in longer technologies (0.18 or 0.3 um) that I could use to do some simple simulation. I would like to get some ballpark values about a simple folded cascode amplifier (1/f, noise, transconductance, bandwidth) to check if it is viable to do what I need in CMOS. I am especially interested in 1/f noise magnitude and corner frequency.
I do not really need exact numbers or extracted parasitics for that matter. If first result would make sense I will contact the design house to finalize the circuits with full simulations etc. I had access to Cadence software in the past, so I lost it long time ago when I graduated, so I am looking for the alternative now that I could use with free or trial software.
Thanks for any suggestions!
Edit: based on replies and materials I found in google here are some interesting links, maybe it will help someone in the future:

I work at a startup, we currently use OrCAD. We are looking at expanding our PCB design capability and do layout in-house. I personally like KiCAD and use it for all my personal designs. The price is right and there are some annoyances, but nothing that can't be worked around. I was wondering if anyone has moved their company tool flow from OrCAD or PADS to KiCAD? How was the experience? Was there anything on that you missed by moving to KiCAD?
I'm getting the above error message on an orcad created part, from an Altera Quartus output, for a large BGA.
Here's the full error message:
"#40 ERROR(ORCAP-36041): Duplicate Pin Name "RESERVED_INPUT_WITH_WEAK_PULLUP" found on Package IC_FRANK_ALICE-3 , U1-1: Schematic, 08 - Alice Trim, Dim, RX Comms (8.90, 9.10). Please renumber one of these."
That net does exist on U1-1, it was a no connect. However, it does not exist on U1-3 (IC_FRANK_ALICE-3) on page 8.
I renamed it on U1-1 so that the pin wouldn't exist at all, and the net extract still produces the same error message.
I also checked to make sure the pin numbers are duplicated, and they are not.
Has anyone seen anything like this before?
Its like there is a database that's not been updated... I wonder if I should clear the intermediate files or something...
UPDATE: my layout genius found it. On the Create Netlist -> Setup Page, there is an option under "Miscellaneous" to set the limit for net / pin names. By default, on past versions of the software, the limit was set to a max of 31. 17.3 allows up to 256, but because I started with an old schematic, my limit was set to 31, so it was truncating the signal names so they were all the same. I just have to increase the limit.
