ModelSim AE 10.1d Warning

Hi,

I'm getting this warning and have no idea what this means. I am running a licensed version of MS.

# ** Warning: Design size of 365 instances exceeds ModelSim ALTERA recommended capacity.

# This may because you are loading cell libraries which are not recommended with

# the ModelSim Altera version. Expect performance to be adversely affected.

Any insight would be helpful.

    Yes. The AE licence is limited, so when you have too large a design, it slows down simulation.

    you didnt pay for the full version of modelsim though. IIRC, AE only comes with a Quartus licecnce.

    Hi,

    I am also seeing similar error when running ModelSim Altera Edition 10.1d on a design developed in Quartus II web edition:

    # ** Warning: Design size of 6 instances exceeds ModelSim ALTERA recommended capacity.# This may because you are loading cell libraries which are not recommended with# the ModelSim Altera version. Expect performance to be adversely affected.

    Why has it something to do with Quartus II version we are using??

    What's the difference of this AE version then from the ASE version? This is frustrating...

    Hi,

    We also got the same warning when we are trying to compile altera libraries. When we receive this error, it is not just warning, it increases your design execution time as well. ASE-Altera Starter Edition (No License required, Limitation in design size), where as AE-Altera Edition (License required, No Limit in design size). You can find basic differences in this link. http://www.altera.com/products/software/quartus-ii/modelsim/qts-modelsim-index.html.

    However, we get the above warning in both editions when we are trying to compile altera libraries. Please avoid to compile the libraries, instead you can import required libraries using below command.

    vsim -t 1ns top -L 220model_ver -L altera_mf_ver -L sgate_ver

    ns: time scale

    top: top-level module in your design

    all others are required libraries according to your design. Here, _ver indicates verilog libraries.
