But my compile times were going from 52 seconds to 1 min 11 seconds therefore I switch back to V13.1.0.
(I did that upgrade a couple of weeks ago. The problem went away when i upgraded my quartus ii web edition from v13.1.0 to v15.0.0. The only problem was with the simulation.
It is worth mentioning that I could download the program into my Cyclone V Starter Kit and everything would run as programmed. I tried copying folders and files to folders that I knew the Quartus II and ModelSim was linking to. I tried adding directories using Tools/Options/Libraries. If I disconnected the PLL's, simulation of the program with the ROM:1-Port would give# ** error: (vsim-3033) nofile(37): instantiation of 'generic_m10k' failed. But when I used MegaWizard to create ALTPLL, Altera_pll or ROM:1-PORT components, I would get the above error messagee for the PLLs when I simulate. I found that I could simulate the program with no problems when I used MegaWizard to create components LPM_MUX, LPM_MULT and LPM_ADD. I am using schematic entry to create my schematic (.bdf file). I wanted to share details of the problem and solution with the Forum. when I have run ModelSim-Altera Starter Edition.
I had a similar problem in which I have been getting error# ** error: (vsim-3033) alstimschem.vo(825): instantiation of 'altera_pll_reconfig_tasks' failed. When I execute the do script, modelsim just open-up the PWM_Gen.vo file, without running simulations on it. Should I put the PWM_Gen.vo as the testbench file? \QuartusII\simulation\modelsim folder (PWM_Gen is the name of the top module): Here is the screenshot of all the files in. However, I'm not really sure about the testbench file that you mentioned. The "the design unit was not found" error has been solved. Substitute the location of your version of Quartus in place of "C:/altera/14.1" and the name of your test bench as appropriate. cycloneive_atoms C:/altera/14.1/quartus/eda/sim_lib/cycloneive_atoms.v In the ModelSim console, or in your tcl script, add: You need to add the 'cycloneive_atoms' library to your simulation. 0quartusedasim_lib # ** Error: (vlog-7) Failed to open design unit file ".0quartusedasim_lib" in read mode.ĭid I mistype anything in that vlog command?ītw, I'm also using QuartusII 15.0 Web-Edition.
