Occasional ContributorEMIF 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!
one more thing ,I have generated emif core. With Avalon bus signal I am trying to feed some data,in this case aslo calibration is not going high.

Hi K Venkatesh,
The Abstract PHY mode, Skip Calibration mode and Full Calibration mode are take action on Simulation.
The design has same structure and can be tested on board.
If you want to observe the design in simulation, then you can choose either Skip Calibration or Full Calibration mode.

VenkateshKThankyou so much for clarification!
I was trying to Implement EMIF DDR4 .but its not working properly.Here's the few issues- local_calib_success is going high ,immediately the controller(amm_ready) is going to busy state(high).
- after some time loca_calib_success going to low ,immediately emif_user_reset_n is going low
if possible ,could you please share Code for instead of Traffic generator for testing DDR4 instead of Traffic generator
I have attached a snapshot regarding this.- VenkateshK
Hi,
Can you please simulate without Abstract phy and share the result ! as well as design!?
I have tried simulation without enabling abstract phy ! but didn't get any thing!
Thankyou.

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.

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
