Beginners question in multiple assignments to output - Beginners question in multiple assignments to output Hi everyone, I would be interested in assigning two wire variables to a single output pin and obtain as an output signal the summation of the two signals. A trivial example would be to use the clock signal CLK_50 and NOT(CLK_50) and send them both to the same output to obtain a constant high-level voltage corresponding to the summation (not in the Boolean sense) of the two signals. Do you know if this possible to combine signals to outputs this way ?

The problem is already marked as "solved" in the feed, but somehow I cannot put any kudos to this user for the answer provided (I do not why it does not work). Thank you again for your help and support.

Also, would it possible as a moderator that you are not using my first name from my account information but my username FPGA_FR in public post ? Is it possible to edit that out from your previous message ? Thank you very much for your understanding on this matter. Thank you all for your help on this forum. Very much appreciated Best wishes, Replies: Re: Beginners question in multiple assignments to output Hi FPGA_FR, May I know if there is any update from previous reply? Replies: Re: Beginners question in multiple assignments to output What you seem to be asking for is analog logic, summing the levels on two wires to produce an output signal that can have three discrete levels. IE: (0,1) + (0,1) = (0,1,2) This is not possible in digital logic FPGAs. At best you could two outputs and resistors to simulate a simple digital to analog converter, much like some development boards support an analog VGA signal using an array of resistor values R-2R-4R-8R etc to make a simple D to A. Can't be done internal to a device however. Not with any current Altera FPGA parts AFAIK.
