Honored ContributorSimulation problem: altera_pll - The design unit was not found
Hello
I create a simple project to practice Quartus II (v13.0.1) A simple design include a PLL that generated by MegaWizard when I simulate my design using ModelSim ALTERA STARTER EDITION 10.1d I got an error message-------------- # Loading work.rt0_top# Loading work.ip0_pll# ** Error: (vsim-3033) D:/jamieliao/Try_QuartusII/Megafunction/ip0_pll_sim/ip0_pll.vo(51): Instantiation of 'altera_pll' failed. The design unit was not found.# # Region: /rt0_top/IP_0# Searched libraries:# D:/jamieliao/Try_QuartusII/Project/simulation/rtl_work# Loading work.rt1_pll_rst_flow# Error loading design I found altera_pll.v file at ...\13.0sp1\quartus\libraries\megafunctions\altera_pll.v I was wondering to know how to link the libary file to simulator. Is there a properties setting that can let all the magafunctions link to simulator automatically. thank you Jamie3 Replies
Altera_ForumHi,
why don't you remove the pll instance just for the simulation ? Otherwise, I think you should update and compile altera libraries under modelsim. (but i'm not sure that one can simulate a pll..) regards, PS : may be a particular device pll could be simulated (ex : cyclone_pll).- Altera_Forum
Hello,
I was also facing same problem and I could solve it by adding "altera_lnsim_ver" library. ( This library is for verilog. And same can be found for VHDL. ) I was simulating Stratix V device in Quartus 13.1. Hope this would be helpful to someone.

But I could not adding altera_mf_ver( included alt_pll also). Have you any solution for this problem? Regard, ToanRV.
