molex connectors?

[pgo48]

Hi, I've just started using multisim/ultiboard. I simulate my design with potentiometers, but instead of connecting the pots into the board I want to break out with a molex connector.

a) Is there a quick way of doing this without disconnecting the pots and replacing with a connector so I can go back to the multisim design and test it

b) is there a library for molex connectors? i can't find it....

pgo48,

Yes, when you select the potentiometer you can choose the "no footprint" option and the potentiometer will not be physically present in the layout.

When wiring the connector, place the connection in parallel with the potentiometer (since the connector does not have a model but the potentiometer/resistor does, this circuit configuration can be used for both interactive simulation and layout.   Here is a simple divider network to illustrate this (note the color coding of Multisim components to indicate model only (black), footprint only (green), or both (blue).   You can also click on the parts and see whether a model or footprint is included in the properties.

b) is there a library for molex connectors? i can't find it

We do not have a specific Molex library.   There are many types of molex style connectors - is there a specific type (part number) or family you are looking for?   Perhaps another user has created a specific one that you can also use.   If not it is relatively easy to create a simplified land pattern and map it to one of the existing connector symbols.  Also note in v12 we did add many new connector parts and we are interested in creating more connector style parts, please let us know of specific families that would be of interest and we'll research the direct creation/inclusion in Multisim/Ultiboard (more likely if it will benefit many users).

Note that if you want to create a 'placeholder' in your schematic, you can use one of the more generic "header" type connectors that match the pin count and later on when you do your layout, create the actual footprint shape and map it to the same symbol.   (Then to sync up the layout, you just do a replace in Multisim with the correct part and forward annotate the design into Ultiboard).

in v11 and prior: Master DB->Basic->Connectors,

in v12: Master DB->Connectors->Generic

thanks for your answer. I realised the connectros im looking for are in the connectors folder! thanks again
