[Altera_Forum]

When 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

What version of Modelsim are you using (SE or Altera edition?).

[Altera_Forum]

modelsim 6.1g(Altera)

[Altera_Forum]

Have you checked in the library tab in Modelsim that the altera libraries are correctly installed?

[Altera_Forum]

Is 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.

[Altera_Forum]

And sometimes these kind of errors come up if the Quartus II and Modelsim version numbers are not the same.

I 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..

I compile the two library files:altera_mf.v and cyclone_atoms.v

--- Quote Start ---  I compile the two library files:altera_mf.v and cyclone_atoms.v  --- Quote End ---    Are they complied into and mapped to the write library?  Reading up on modelsim vmap command might put some light on it :confused:  This might help too..  http://www.altera.com/support/kdb/solutions/rd02012002_3673.html?gsa_pos=1&wt.oss_r=1&wt.oss=sdf%20files%20require%20altera%20primitive%20library
