simulating PLL in Modelsim

Honored Contributor II

I have created a PLL megafunction in quartus II, and it created a vho file in Modelsim and even successfully opened up Modelsim from this environment. Here's the rub: I created a new project in Modelsim. I opened the vho file. I compiled all, which was successful. I created a new work library so that I can see the existing library, rtl_work ( I don't know any other way to open an existing library in Modelsim PE). I selected the compiled file and when I request "start simulation", I get a message that the Student version only supports 1 HDL. But I don't have any other Modelsim running. How do I successfully run Modelsim of one PLL? 

I am including the transcript if it may help you understand my problem.

I was able to access the Work view. However that still does not solve the problem. Modelsim is saying that this project requires multiple HDL. I have the Student version which allows only one HDL. I am not sure what I may be doing wrong. I am attaching the Modelsim transcript:

Can you try with Modelsim Altera Starter edition which is free.


I'm facing the same issue. Were you able to solve it?
