    Hi rbugalho,

    i've tried with LPM COUNTER but i don't reach my goal.

    I attach the origina schematics and the bdf file of my project.

    Can you help me to terminate to build the counter in the project file?

    Thank You in advance.

    There isn't anything in the library that will behave exactly as the 40103.

    So, you need to build your own.

    You can try do design a sub-block that behaves as the 40103 using the LPM_COUNTER and some more gates.

    Or you can write a Verilog or VHDL module that behaves as the 40103.

    Then, after you create the symbol for it, you can add it to your schematic.

    Something like the attached file -- I didn't test it!
