Did you figure out how to solve this? I am having the same error with altera_pll supposedly unbound.

Hi,
To solve this trouble, you have to modify the altera_lnsim_components.vhd file. Copy this file in local and do the following modification:
Extract of the code of the altera_pll component
pll_vco_div :integer := 0;
pll_output_clk_frequency :string := "0 MHz"; -- Paste the original code here
pll_bwctrl :integer := 0;
pll_cp_current :integer := 0;
pll_fractional_division :integer := 0;
pll_fractional_cout :integer := 24;
-- pll_output_clk_frequency :string := "0 MHz"; -- Original code
