Help programming CPLD with graphic editor

Hi to all

I'm starting using CPLD with MAX plus II and Quartus graphic editor.

I know It's not the best way but It's the easyiest for starting.

No problems with logics, inputs and outputs.

Now I like to add a ROM in my design.

I need a size equal as a 27C128.

I dont manage to do it and help will be really appreciate.

I'm french so sorry for my poor english :oops:

    The 27C128 requires 128K bits of memory. I'm not aware of any CPLD that has enough resources to support this. To answer your question though, "double click" on an empty place on your top level schematic, choose "MegaWizard Plug-In Manager", follow the instructions until you can select from a list of memory components in the "Memory Compiler" folder.

    Thanks you very much gj_leeson.

    I'll try FGA in Quartus then.

    I make a new projet in MAX+ but I don't have HEX file.

    My file is a ROM.

    Sorry but I need more help :oops:
