Quartus II mux for schematic entry?

Altera_Forum · ‎08-22-2007

Sorry for the newbie question:

I have Quartus II 4.2 Web edition.

I don't see a multiplexer symbol in the Quartus library, unless I open the Max II folder. Ok to use the Max II 74 series libraries?

Thanks

Hmm. No design files for MaxPlus logic cells.

Guess I have to make a mux from AND and OR gates?

Have you tried looking under megafunctions/gates/ ?

Clancy:

I placed "BUSMUX" into my desgn. I set the "width" parameter to 8, then double clicked on the mux icon, error message says:

Can't locate design file for entry "BUSMUX"

Use lpm_mux.

Make sure you have "Launch MegaWizard Plug-In" check box selected.

Press OK.

Select your HDL language (it will autogenerate a wrapper in the language you select).

Press Next and enter the mux parameters. Continue to Finish.

I hope this helps :)

Always use lpm_ library components if available.
