Hi, all
According to this article at emi_debug.pdf on page 8: Table 1–1. Typical Simulation Times Using UniPHY IP, skip calibration should take only 3 minutes. My DDR3 UniPHY design is very basic with 8 bits read and write operation. I use generated example design for simulation. For my case, I choose skip calibration mode and also disable the EMIF On-Chip Debug Toolkit in Diagnostics tab of the UniPHY-based controller MegaWizard GUI. http://www.alteraforum.com/forum/attachment.php?attachmentid=10311&stc=1 Figure below is ModelSim starter 10.3c waveform simulation. To get overall complete simulation (110us), my computer took about more than 30 minutes to complete it. http://www.alteraforum.com/forum/attachment.php?attachmentid=10312&stc=1 May I know how to reduce the simulation time as stated in 3 minutes? Any example design file i need to reedit? Thanks!

The altera starter edition has the slowest simulation speed. For faster simulations, you need to purchase a better licence. The more you pay, the faster the simulation.

Hi, Tricky
Thanks for reply. --- Quote Start --- The altera starter edition has the slowest simulation speed. For faster simulations, you need to purchase a better licence. The more you pay, the faster the simulation. --- Quote End --- May I know what is the better licence version to boost the simulation speed? May I know where to see the license price? Here's my findings. By referring to the link below: https://www.altera.com/products/design-software/model---simulation/modelsim-altera-software.html I found out that payable ModelSim-Altera Edition Software, it only improve 33 % faster simulation performance than ModelSim®-Altera® Starter Edition software. Also, may i know what is line limitations mean? For ModelSim Altera Starter pack, the line limitation only up to 10k.- Mark as New

That is just the ALtera Edition. You will get Speed up from a full Questa Licence. But this will be a few thousand $.
You need to speak to your distrubuter about licencing.- Mark as New
