Honored ContributorWhen I use modelsim to simulate,always find error as follow:# Loading work.CYCLONE_PRIM_DFFE# ** Fatal: SDF files require Altera primitive library# Time: 0 ps Iteration: 0 Instance: /wave_top File:
D:/cyclone/fpga/sinwave/simulation/modelsim/wave_top.v# FATAL ERROR while loading design# Error loading design
Honored ContributorWhat version of Modelsim are you using (SE or Altera edition?).
Honored Contributormodelsim 6.1g(Altera)
Honored ContributorHave you checked in the library tab in Modelsim that the altera libraries are correctly installed?
Honored ContributorIs the licence installed correctly? Do you have another free version of modelsim from another FPGA vendor installed? There can sometimes be a conflict between the licences.
Honored ContributorAnd sometimes these kind of errors come up if the Quartus II and Modelsim version numbers are not the same.
Honored ContributorI dont think it is the problem with the license. Please compile all the device specific libraries with the your modelsim, and ensure that you have all the libraies compiled before you simulate..
Honored ContributorI compile the two library files:altera_mf.v and cyclone_atoms.v
