Unable to simulate GPIO DDR on modelsim 10.1d version.

Hi,

above youtube link helped me but the problem with DDR simulation still same. I was trying create new project in modelsim and run simulation after adding relevant libraries but I am getting same error both the way i.e. Nativelink or modelsim.

vsim -L altera -L lpm -L sgate -L altera_mf -L altera_lnsim -L fiftyfivenm -L fiftyfivenm_ver -L rtl_work -L work -L ddr_module -L DDR_Data -voptargs=\"+acc\" -t 1ps work.t2

# vsim -L altera -L lpm -L sgate -L altera_mf -L altera_lnsim -L fiftyfivenm -L fiftyfivenm_ver -L rtl_work -L work -L ddr_module -L DDR_Data -voptargs=\"+acc\" -t 1ps work.t2

# ** Error: (vsim-19) Failed to access library 'fiftyfivenm_ver' at "fiftyfivenm_ver".

I tried in VHDL coding and just added one IP i.e DDR and have done simulation and above error it occurred.

Thanks
