[ENGINEER(ASM)]

When I tried to use ,multiplexer,Mux 4to1 in , Multisim v11.0 , I found that the order of selection line inputs pin name is (c,b,a) and I usually use the inverse order so Could you help me to edit pin name or to exchange A , B,C pin names to get the usual order I use

thank's in advance

Hi,

Use the Component Wizard under the Tools menu to recreate this part.   Here are some suggestions when going through the wizard:

Step 1:  Select Simulation only and in Component Type: select Digital and Til under Component Technology

Step 2. Just press Next

Step 3. Select Copy from db and select the MUX 4to 1 from the Master Database, next select Edit to launch the Symbol Editor where you can modify the symbol.  Don't delete any pins, you can rename or re-order the pins

Step 4.  Setup the pin type, pin Y and ~W are outputs everything else are inputs 

Step 5.  click Select from Db and again select the MUX 4 to 1 to use that model

Step 6.  Mapping the symbol order are shown below, pin ~G = 1, B-2.... ~W = 9

 ~G B A D0 D1 D2 D3 Y ~W 

Step 7.  Save the part to your database.
