Error (12002): Port "byteenable2" does not exist in macrofunction "onchip_memory" - Error (12002): Port "byteenable2" does not exist in macrofunction "onchip_memory" Description Due to a problem in the Quartus® II software version 13.0, the dual port RAM (on-chip memory) component in Qsys incorrectly adds the signal byteenable2 on slave s2 when the data width is set as 8 bits. Resolution To work around this problem, perform the following steps: Open the file altera_avalon_onchip_memory <instance> _hw.tcl in a text editor and comment line 671. #add_interface_port s2 byteenable2 byteenable Input Add the following lines under line 671: if { > 1} { add_interface_port s2 byteenable2 byteenable Input } Refresh and regenerate the system This problem is fixed beginning with the Quartus II software version 13.0 SP1.
