Technology map viewer post-fit equation operators

Hello,

I am using Quartus Prime Version : 18.1.1 Build 646 04/11/2019 SJ Standard Edition. I am reviewing the post-fit map of the design I am debugging. The logic_cell_comb of interest has the following equation:

<c> write_request~0
 = DATAE & !DATAF # !DATAE & !DATAF & (DATAB & !DATAC $ (DATAD))

I need to know the definitions of the operators # and $.

Is there a list of operator symbols that define the operations?

Thank you

    Well for what it is worth, in CUPL the logic operators are, in order of precedence (high to low):

    ! NOT
    & AND
    # inclusive OR
    $ exclusive OR

    Hmm I haven't see this before.

    May I know where do you get this equation from the technology map viewer?

      I highlighted the logic_cell_comb box so that the border of the box is red. I right click and select properties. The properties display on the left side of the window where the netlist navigator and find windows display. The properties window has the equation tab. Shall I send you a screen shot?

    Thank you. I was guessing # and $ were OR operations but the symbols do not intuitively indicate which is which. I looked CUPL up and I can see where it could be used in the mapper process.
