EMIF DDR4 STRATIX 10 ,QUARTUS PRIME PRO 20.1

Hi, I have Generated example design for emif stratix 10 and simulation scripts too. While simulating in the modelsim ,every signal has default values only. even calib_success&fail both were low only...

Hi K Venkatesh,


How many timeline that your simulation has been running?

I think that the Skip Calibration mode simulation will take a longer time than the Abstract PHY mode.


This is the result from my simulation for Skip Calibration mode.

It's taking hours for now and not finish yet.

But it's expected a behavior when simulating with Stratix 10 device.


You can generate the example design from the .qar file that I've shared before but you need to disable the Abstract PHY mode first.


Are you referring to this user guide when implementing the design?

I'm not able to provide the code to replace the Traffic Generator.


Regards,

Adzim

    Sir, thank you so much for your support ,I Have simulated till 150,00,000 ps. Now I understood that It takes morethan 300,000,000 ps

    I will simulate that again and update you.

    while testing emif on custom card I am facing some issues:

    please have a look
