Honored ContributorHello,
I have to use a pll in my design. so I've created a pll via megawizard with my needs. 100Mhz clock input and 5nsec shifted clock in the output. now, I want to simulate my design with modelsim. how can I do that? where should I place the PLL.vhd component, I put it inside top.vhd and i am getting errors "Unknown identifier" to all pll I/Os. can you assist?
Honored ContributorHello,
Wrap it inside an entity that is then instantiated in your testbench. Keeps the same entity as top in Quartus. Don't know how correct it is - but it works for me :) M.Honored ContributorMy design hierarchy is : TestBench -->top level-->Pll
did you do the same?Honored ContributorYeah, pretty much. Modelsim needs an altera library to simulate their things tho, altera_mf if I remember correctly. When defining you pll in the megawizard you need to check off that one also.
Honored ContributorIt works,
Thanks!!!:)
