Technology map viewer post-fit equation operators - 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 Replies: Re: Technology map viewer post-fit equation operators I’m glad that your question has been addressed. With that, I will now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you. Best Regards, Richard Tan Replies: Re: Technology map viewer post-fit equation operators FYI also found this table of operators in the help file for the Altera AHDL language. https://www.intel.com/content/www/us/en/programmable/quartushelp/13.0/mergedProjects/hdl/ahdl/ahdl_elements_arithmetic_expressions.htm Same definitions of ! & # $ apply. Replies: Re: Technology map viewer post-fit equation operators 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. Replies: Re: Technology map viewer post-fit equation operators 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 Replies: Re: Technology map viewer post-fit equation operators 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? Replies: Re: Technology map viewer post-fit equation operators Hmm I haven't see this before. May I know where do you get this equation from the technology map viewer?
