20 years agostripping out old library paths
In the readme.txt file contained in the example for altera\kits\nios2_51\examples\vhdl\niosII_cycloneII_2c35\standard, there was the following caution at the end:
<div class='quotetop'>QUOTE </div> --- Quote Start --- - Due to the library paths that are coded into the Quartus settings for this project, if a user wishes to modify the hardware design they must first strip out any old paths from within the project settings file (qsf). An example of this is as below: set_global_assignment -name POST_FLOW_SCRIPT_FILE "quartus_sh:auto_verify_ddr_timing.tcl" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_tb_functions.vhd" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_functions.vhd" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_input_buf.vhd" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_timers.vhd" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_avalon_if.vhd" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_bank_details.vhd" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_controller.vhd" set_global_assignment -name VHDL_FILE "C:/MegaCore/ddr_ddr2_sdram-v3.2.0/lib/auk_ddr_init.vhd" set_global_assignment -name VERILOG_FILE "C:/niosII_cycloneII_2c35/full_featured/ddr_sdram_auk_ddr_dqs_group.v" set_global_assignment -name VERILOG_FILE "C:/niosII_cycloneII_2c35/full_featured/ddr_sdram_auk_ddr_clk_gen.v" set_global_assignment -name VERILOG_FILE "C:/niosII_cycloneII_2c35/full_featured/ddr_sdram_auk_ddr_datapath.v" set_global_assignment -name VERILOG_FILE "C:/niosII_cycloneII_2c35/full_featured/ddr_sdram_auk_ddr_sdram.v" set_global_assignment -name VERILOG_FILE "C:/niosII_cycloneII_2c35/full_featured/ddr_sdram.v" set_global_assignment -name PRE_FLOW_SCRIPT_FILE "quartus_sh:auto_add_ddr_constraints.tcl" Once these have been removed regenerate the embedded system in SOPC Builder to recreate new paths for the DDR on the local machine.[/b] --- Quote End --- I noticed when I moved a project using the .QAR file in Quartus 5.1 SP1, the resultant .QSF file didn't appear to contain these absolute path references. Am I correct in assuming that this is something that is fixed and I can ignore the instructions in the readme.txt? - Jim
