Ultiboard: BGA Fanouts

Status: New Submitted by Member on 10-27-2016 07:32 AM Comment

Hi,

This is my fourth advise about Ultiboard ideas.

We should have better FANOUT BGA routing in the ultiboard. The current one does not work well and is not able to complete BGA Fanouts. Everytime I should draw it manually to have better and complete Fanouts.

Ultiboard: track shoving

Status: New Submitted by Member on 10-27-2016 05:19 AM Comment

Hi,

 

This is my third post about Ultiboard and I have an advise if Ultiboard Team listens.

 

Ultiboard should have Track and Via Shoving function to have more proffessional CAD design tool. This is really annoying without this function especially when we draw small pcbs of BGA design.

 

Thanks,

ERC

Open Circuits

Status: New Submitted by Member on 08-31-2016 10:51 PM Comment

Recently in class we were using the Signal Generator and the Bode Plotter.  It made it somewhat difficult to get the correct readings because the live version does not include an option to place an open wire (was using it on an op amp) like in the application version.  It also made it somewhat difficult to change an AC current when involving different equations. Overall I like the Live version.

Multisim Live: Move Probes with Wires

Status: New Submitted by Active Participant on 08-31-2016 10:24 AM Comment

After placing some probes on my circuit, if I move any of the components, the attached wires will move accordingly, but the probes will not. Therefore they are no longer connected to the wires and need to be reconnected manually. I would like for probes to be attached to the wires and move along wtith them when moving components.

Make "MultSim Live" a part of any electronics textbook (maybe with "mini-subscriptions")

Status: New Submitted by Member on 08-18-2016 03:12 AM Comment

Hello,

 

I am a noob in electronics and are following along one the popular
books: "Make:Electronics", but this idea is applicable for any textbook in electronics.

 

make1.jpg

 

Besides actually "breadboarding" the exercises in the book,  i would like to simulate them to get the hang of that side of things also, and after a lot of research, the web interface of "MultiSim Live" seem to be the perfect alternative.

In my case because the "2N6027" PUT component is missing from most competitors, but exist in Multisim Live Premium, and many excercises in the book depend on it.

 

Here is the idea:

 

Would it not be nice if the author could create a temporary subscription in Multisim Live for its subscribers, where only the components in the book are included?

 

The subscriber would still have to pay for it, but for a much smaller price, since it is only make sense if you have the book.

Pros:

- Multisim Live would get great advertisment since the product is referred to throughout the book.

- Beginners like me would not have to worry that we dont find the correct components , since they are listed when you login to multisim with this special subscription package.

- Of course, the author could have pre-made excercises in Multisim live to drive home points

- The opportunities for converting these subscribers to premium subscribers would be endless

 

Cons:

Absolutely zero

 

Please NI make this happen, its a no-brainer 🙂

Increase the library of Microcontroller in Multisim

Status: New Submitted by Member on 07-20-2016 02:15 AM Comment
Increase the library of microcontrollers like PIC, AVR Atmega in Multisim. There is Proteus software available which already have a vast library, but I like Multisim Environment and don't want to move to Proteus.

Ultiboard: Stop automatic glueing of parts to gudelines

Status: New Submitted by Member on 07-04-2016 07:50 AM Comment

Currently (Ultiboard 14.0) parts automatically glue to guidelines if one 'catches' a part center when placing a guideline. Then. when a part is glued, it moves along with the guldeline.

 

 When one works on a precise part of layout and aligns components using guidelines, guidelines can catch parts in other part of the PCB and destroy layout there. Please disable this feature or at least make it optional.

Ultiboard: Polygon creation improvement

Status: New Submitted by Member on 06-06-2016 02:37 AM 2 Comment

It would be good to allow undoing polygons vertex by vertex. Now when one makes a mistake when laying up a polygon, he/she has to cancel the drawing and start over. It would be a big improvement if there was an option to remove the last created polygon vertex.

Hierarchial Block as a User Component in Component Library

Status: New Submitted by Member on 06-04-2016 03:07 AM Comment
I know Hierarchial Blocks are helpful for circuit diagram reduction, but it is uneasy to browse & safe keep the hierarchial block file every time I need it. So it would be better if there's any way to convert the hierarchial block for into a permanent spice component in the user database of the component library. So is there any way?

Histogram for Fourier Analysis

Status: New Submitted by Member on 06-04-2016 02:03 AM Comment
Current version of Multisim doesn't allow to view the Fourier Analysis Magnitudes in the form of Histogram. I hope it does in upcoming version.

Ultiboard: Fix part selection

Status: New Submitted by Member on 05-09-2016 03:05 AM Comment

Make part selection select parts only on active layer. It is very frustrating when Ultiboard selects and drags e.g. a connector on Top layer along with (intended to be deragged) a resistor on Bottom. Ultiboard also selects locked parts on inactive layers, in situations like in the attached screenshot. I can select the locked part (which is SMT part placed on Top) when dragging parts on Bottom - this is VERY frustrating...

Multisim PLD Configuration Files for the Digilent "Nexys 4 DDR" FPGA Board

Status: New Submitted by Member on 04-29-2016 03:24 PM Comment

A very useful improvement to Multisim would be to include support for the Digilent "Nexys 4 DDR" FPGA Board. Multisim 14.0 supports the "Nexys 4 DDR" board (no longer manufactured) but not the new "Nexys 4 DDR" (which replaces thr older one).

 

Alternatively, Multisim PLD Configuration Files for the Digilent "Nexys 4 DDR" FPGA Board should be made available.

Fix the group text attributes defect in UB

Status: New Submitted by Active Participant on 04-01-2016 02:03 PM Comment

In UB when a selection of multiple text objects are grouped most of them just dissapear.  They do not re-appear when the group is ungrouped.

 

This is a pain when mutiple structures with text objects exist and need to be replicated in a design.

 

I reported this as a bug a couple revs back when I was a beta tester and was told it was fixed for the next rev, but it was not.  I updated the defect report with that info, but noone seems to have noticed.

Fix UB export layer stack report

Status: New Submitted by Active Participant on 04-01-2016 01:44 PM Comment

The report does not generate correctly if you don't have all the layers hard selected first in the design toolbox.

 

I believe this should be considered an error.  The layers exist and should be properly reported, whether they are enabled in the Design Toolbox for viewing or not.

Provide for renaming files directly in the toolbox project view

Status: New Submitted by Active Participant on 03-24-2016 11:43 PM Comment

 

This would make managing files in a project that much simpler.  As it is now you have to go into windows explorer, rename the file, go back to the toolbox, click on the file, navigate to and select the new file after it tells you it can't find the file anymore.

 

Just a right click/rename would be so much smoother.

Highlighting net on multiple sheets - Multisim

Status: New Submitted by Member on 02-20-2016 06:52 PM Comment

New feature proposal:

 

Frustrating is the number of button pushes necessary to see a net on multiple sheets/

 

example

 

Net appears on two sheets

 

currently have to select sheet to see net.  To see on next sheet have to select sheet.

 

Selecting takes time.

 

Would be great if   after selecting the RED arrow, that space bar would go to next sheet to see net.

 

Sounds trivial, Upverter shows how they have done this, and then in Altium, one of the so called top csd tools, their tool requires one third mouse clicks.  They even have people in house analyzing how to reduce clicks to help user to save time.

 

Ultiboard could have this feature and be the premier Circuit Design Suite.

MAX1978 & ECL MC10EP05 missing in Multisim

Status: New Submitted by Member on 02-18-2016 06:15 AM Comment

Good day

Can you please add these important components in Multisim 14 as I consider thm extremely important. MAX1978 is a smallest safest most accurate single temperature controller for Peltier Thermoelectric cooler while MC10EP05 is an ideal pulse shaper where duty cycle skew is critical.

I would like to know how soon can this be done. I am on a extremely tight timeline.

 

Please help.
