I'm trying to build system for DE0_Nano board using Qsys (QuartusII, 11.1 SP2).
System preparation and generation by Qsys are passed without errors, but Quartus Analysis&Elaboration give fatal errors (12006): Node instance "XX" instantiates undefined entity "DE0_N_QSys_XX" only for some included entities. More details below. Project setting: Device: Cyclone IV E device EP4CE22F17C6; Files : ProjDir/Test_0 // Top-Level entity ProjDir/DE0_N_QSys/synthesis/DE0_N_QSys.qip /DE0_N_QSys.v /submodules/...... System consist of the following components: 1. clock Source (nameed as clk_50) 2. Nios II/e CPU (cpu) 3. JTAG UART (jtag_uart) 4. On-Chip Memory RAM (onchip_memory2) 5. System ID (sysid) 6. Parallel i/O [7:0] (led) //8 LED's 7. Parallel I/o [3:0] (sw) //4 switches 8. Parallel I/o [1:0] (key) //2 keys Qsys generation passed with 0 errors and 2 warnings: Warning: system: "No matching role found for jtag_uart:avalon_jtag_slave:dataavailable (dataavailable)" Warning: system: "No matching role found for jtag_uart:avalon_jtag_slave:readyfordata (readyfordata)" After creating the system named as DE0_N_QSys and closing Qsys Quartus starts Analysis&Elaboration. Everything going smoothly but then errors appear: Error: Quartus II 32-bit Analysis & Elaboration was unsuccessful. 5 errors, 5 warnings Error: Peak virtual memory: 311 megabytes Error: Processing ended: Mon Mar 14 23:50:20 2016 Error: Elapsed time: 00:00:47 Error: Total CPU time (on all processors): 00:00:09 Error (12006): Node instance "sw" instantiates undefined entity "DE0_N_QSys_sw" Shortly (the same for all 5 errors (12006)): 1. sw -> "DE0_N_QSys_sw" 2. onchip_memory2 -> "DE0_N_QSys_onchip_memory2" 3. led -> "DE0_N_QSys_led" 4. key -> "DE0_N_QSys_key" 5. jtag_uart -> "DE0_N_QSys_jtag_uart" Looking at directory DE0_N_QSys/synthesis/submodules, corresponding verilog files (DE0_N_QSys_sw.v,...) are missing. I gues that is reason of errors. Even using Demontration example from CD included in development Terasic DE0-Nano board, if I recompile it, the same situation happens. Please, help me to solve this problem of undefined entity!- Tags:

Probably you may want to rename your system from de0_n_qsys to de0_n_qsys_sw and re-generate the Qsys system. The Top level qsys takes the name of the <Qsys name>.v.
Or you can change the sw instance to DE0_N_QSys.- Mark as New

Have you included the .qip file for your QSYS system in your project files.
Don't include the .qsys file though, as that regenerates the system each time you compile.- Mark as New

Thank all of you for quick answer and sorry for long delay of my answer since I was extrimly busy with others.
Problem was solved by using QuartusII, 13.0 instead of QuartusII, 11.1 SP2
