While I enter the values in Xilinx and run syntax check, it shows the Error “Physical unit does not denote a physical type” Can you please have a look. I am attaching my qll file also.

Some more information about the error would be useful too. Umberto February 26, 2019 at 2:15 pm #1740 Saurabh KumarParticipant Please find attached the files. Thanks Saurabh Attachments: andgate.qll 4to2compressor.qll February 27, 2019 at 1:17 pm #1743 FabrizioModerator Hi, you are getting this error because one of the signals is named “sec”, which is a VHDL keyword for seconds.
