I was told I should post this idea here for a greater chance of it being acted upon.  The original discussion is http://forums.ni.com/t5/Circuit-Design-Suite/Multisim-viewer-and-other-suggestions/m-p/3116428#M1728...

I'm interested to know if there are many others who would be interested in a Multisim viewer.  I'm hoping engineering see's this and it pricks their design creativity.  In my business, it would be very handy to have a low-cost viewer that our techs could use as they trouble-shoot the board.  It's not cost effective for us to buy complete licenses for techs that will only view, but not change the schematic.  Right now we print out the schematics, but not every value is available (it would be too crowded on the schematic) and the comments are hidden.  Plus you can't zoom in on printed paper.  The competition (read Mentor Graphics) have free viewers available.

 

Some other suggestions:

- The ability to have the values of a part pop up when the mouse is hovered over it. (Should be able to be switched off).

- The ability to group parts so that they can be oriented as a group. (Similar to how it is available in the component wizard).

 

These would be great enhancements.  Anyone else think so?

Hello to all,

 

it what nice, if we rotate not only the components but also the complete circuit including the wires.

or we can reflect the schematic.

Dear NI

 

Ideas for NI Multisim software:


1. Schematic: To make an option to lock REFDES during copying circuit to the new sheet.

 

2. Schematic: To add power bias annotation for a components.

 

3. Schematic: To add active probe (see CircuitMaker 2000 solution).

 

4. Schematic: To add operating state annotation for transistors (active, cutt-off, saturated).

 

5. Schematic: To set some min and max limits for a voltage, current or power (they shall be visible in Grapher when you generate the plot). 

 

6. Simulation: To add circuit optimizer with various algorithms: Hooke and Jeeves, Levenberg-Marquardt etc.

For example: I would like to find a resitors values according to voltage limits.

 

7. Simulation: Current Worst Case simulation can not find right solution for a non monothonic functions, so please consider to add Hooke-Jeeves algorithm to find real min and max.

 

8. Simulation: To add Root Sum Squared (RSS) method.

9. Simulation: To add assymetrical tolerances option for a components (resistors, capacitors, voltage and current sources etc.)

 

10. Simulation: To add additional drift tolerance (aging, humidity etc.) option for a components (resistors and capacitors). Please create an option to turn ON and turn OFF additional drifts globally for a whole circuit design and for specific component.

 

11. Simulation: To add component stress analysis but more advanced. The goal is to check maximum dissipated power according to derating power characteristics for resistors according to current operating temperature (TEMP parameter for circuit simulation) and maximum voltage for a components (resistors, capacitors).

 

12. Grapher: To add histogram plots for a Monte Carlo simulation incl. table with data: MEAN, SIGMA, UCL, LCL:

 

  • Normal distribution plot
  • Cumulative distribution plot

13. Grapher: To add option to generate one report for Worst Case EVA, RSS and Monte Carlo.

 

14. Grapher: To add 3D plots (see circuit optimizer).

 

15. Interface: Batched analysis is fine, but it would be a good to see TEMP parameter visible in main window.

 

16. Interface: Fast BOM import for Excel and txt file (incl. some component parameters included value, TC1, max operating voltage and so on). For a quick changes on schematic.

 

17. Simulation: To add Worst Case option to Monte Carlo analysis to check ONLY endpoints values.

 

18. Model: To add a module that can build a component model from characteristics from datasheet (eg. to track output voltage characteristics of voltage regulator and to build behavioral model).

 

19. Model: To improve custom component drawing editor (make it handy and efficient like drawing schematic in Multisim). Current solution takes too much time.

  

The goal of these changes is to focus your product more in professional market where engineers must to find voltage/current limits according to operating temperature limits and component tolerance variation. Your product is good but it might be more oriented to perform these tasks much faster.

 

Regards,

PB

In Ultiboard it is possible to export a 3D IGES, but it is not possible to import these 3D IGES files in to Solid Edge or Solid Works. It would be a big improvement of Ultiboard if this was possible in the next update.

By default the soldermask Top and Bottom for a troughhole Via in Ultiboard are checked. It would be nice if I could select in the global preferences or PCB proberties of Ultiboard what I want for default for all the via's I place on the design.

Now, when my design is ready I have to think that I should uncheck the soldermask Top and Bottom of all via's on the design and when I did that and place a via the soldermask for this new placed via is checked for Top and Bottom.
