QDR II Simulation Using NC Sim

[Altera_Forum]

Hello All, 

 I am having a hard time getting the simulation for the QDR II megafunction going. The simulation tool I am using is NCSim. What I am doing is generating the .v files in Quartus and then porting everything into NCSim. I am not sure why I am having such a hard time with the simualtion. I followed the example provided in the QDRII SRAM Controller Megacore users guide in detail. The following is one of the errors that I am getting when I elaborate my test bench.     ncelab: 05.60-s004: (c) Copyright 1995-2006 Cadence Design Systems, Inc. ncelab: *E,CUVMUR: instance 'QDR_CONTROLLER_tb.top_level.auk_qdrii_mw_wrapper.QDRII_SRAM_auk_qdrii_sram_inst.auk_qdrii_sram_controller_ipfs.avalon_write_interface' of design unit 'auk_qdrii_avalon_write_if' is unresolved in 'auk_qdrii_lib.QDRII_SRAM_auk_qdrii_sram_avalon_controller_ipfs_wrap:module'. ncelab: *E,CUVMUR: instance 'QDR_CONTROLLER_tb.top_level.auk_qdrii_mw_wrapper.QDRII_SRAM_auk_qdrii_sram_inst.auk_qdrii_sram_controller_ipfs.avalon_read_interface' of design unit 'auk_qdrii_avalon_read_if' is unresolved in 'auk_qdrii_lib.QDRII_SRAM_auk_qdrii_sram_avalon_controller_ipfs_wrap:module'.  altsyncram ram_inst  |  ncelab: *E,CUVMUR: instance 'QDR_CONTROLLER_tb.top_level.auk_qdrii_mw_wrapper.QDRII_SRAM_auk_qdrii_sram_inst.auk_qdrii_sram_datapath.auk_qdrii_sram_capture_group_wrapper.auk_qdrii_sram_cq_cqn_group.cqn_inst' of design unit 'stratixii_io' is unresolved in 'auk_qdrii_lib.QDRII_SRAM_auk_qdrii_sram_cq_cqn_group:module'.  qdrii_pll_stratixii g_stratixiipll_qdrii_pll_inst     Any help is appreciated!

Have you noticed that the error message includes a blank character in the hierarchy path? auk_qdrii_sram_cont roller_ipfs 

You should check the generated functional simulation model for that.  Harald

For some reason the script I am using was ommitting the .vo file that is required for proper simulation. Once I got that straighten out all of my errors went away.
