Dear all,
Please help me with this issue: I want to simulate Megafunction ALTPLL in ModelSim, The result of ModelSim compilation is no Error, but the output is High Z The waveform is shown in attached file "PLL_waveform.jpg". (1)The Resolution of Modelsim is set to ps. (2)altera_mf.v and 220model.v are included. Would you please give me a hint or a direction to debug this? Thank you in advance! Best Wishes, WilliamLink Copied

hi,
I go the same problem too. using the DE0-Nano board and follow the ALTPLL and Mux design in the baord user guide. when doing the Modelsim RTL simulation with lpm_ver and altera_mf_ver included, the C0 output just get hiZ. any advice? I convert the bdf to verilog format before using nativelink to trigger the modelsim-altera simulator. the C0 output just show hiZ. dont know why? I attached my project design file here, pls help.
