Create LDS-A414RI 7-Segment Display Component in Multisim

Component Wizard (in "Tools" menu), step 1 of 8.

Component Wizard - Step 1 of 8

Select a a 14-pin DIP footprint fro mthe Master Database.

Select a footprint

Footprint and number of pins entered.

Component Wizard - Step 2 of 8

Step 3 of Component Wizard: Enter symbol information.

Component Wizard - Step 3 of 8

Click on "Copy from DB" and select SEG_DECIMAL_COM_A (7-segment display with decimal point and common anode) from the Master Database.

Select a Symbol: SEG_DECIMAL_COM_A

Component Wizard Step 3 with symbol information entered.

Component Wizard - Step 3 of 8

Component Wizard Step4: Set pin parameters. Leave the settings as shown below.

Component Wizard - Step 4 of 8

Component Wizard Step 5: Set mapping information between symbol and layout footprint.

Component Wizard - Step 5 of 8

Mapping information between symbol and layout footprint entered for LDS-A414RI.

Component Wizard - Step 5 of 8

Component Wizard Step 6: Select simulation model. Click on "Load from file".

Component Wizard - Step 6 of 8

Load the Spice specification for the LDS-A414RI from LDS-A414RI.cir.

Loading Spice specification for LDS-A414RI

Click on "Next".

Component Wizard - Step 6 of 8

Component Wizard Step 7: Set mapping information between symbol and simulation model. Fill in the table for the LDS-A414RI as shown below and click "Next".

Component Wizard - Step 7 of 8

Select the User Database and select the Indicators family group.

Component Wizard - Step 8 of 8

Enter LDSA414RI (or something similar) for the New Family Name.

New Family Name

Then click "Finish".

Component Wizard - Step 8 of 8

Now the new component should be available from the User Database. Place it in a new design and then (under "Properties") select "Display", disable "Use schematic global setting" and enable "Show footpint pin names" as shown below.

Enabling the footprint pin names for the LDS-A414RI component

Now the component should look as shown below (zoomed in for better visibility).

Note that this component has the correct footprint for a printed circuit board design and the correct Spice model for simulation. But it is not animated (i.e., it does not show whether a particular segment is on or off) because the creation of animated components requires a special code that is only available to National Instruments developers.
