How to simulate Megawizard functions in altera modelsim

Hello,

I am trying to simulate megawizard functionalities in altera-modelsim but I get an error saying device is not instantiated. I know that I have to add libraries like 200.v and few others which are specified in the EDA section of the Megafunction. The problem is I do not know how to add those libraries. Can someone please suggest a method?

Regards,

Ranjan

    I am also having trouble with the megawizard libraries. I am getting the error "Failed to instantiate shiftreg."

    I followed the instructions in the link and compiled 220model.v but it still does not work. I need some more hints.

    Did you 'add' the simulation library?

    E.g.:

    vsim -L lpm_ver work.lpm_shiftreg_test

    Hello,

    Make sure that the compiled library is within your work folder. Once that is done then in your simulation tab you should be able to see a lot of modules from the compiled library. Select the testbench (which you had coded) and simulate that.Hope it helps.
