EMIF DDR4 STRATIX 10 ,QUARTUS PRIME PRO 20.1

Hi Sir,

I'm Adzim. Thanks for using Intel Community.

May I have a simulation log from the example design that you have run?

Also, can you share the example design with me?

I want to replicate the issue.

Thanks,

Adzim

I have created example design and generated simulation scripts from Quartus prime pro then simulated through modelsim ,in model sim local_cal_succes is low only.

Basically how much time does simulation takes to complete caliberation (i have used skip caliberation)?

Appolozies! I am not supposed to share any file!

can you please share any emif ddr4 stratix design with model sim scripts whcih are working!

Thanks

Hi Venkatesh,

I think you have to wait until the simulation is finished because there are some calibration that need to be done before the memory is ready.

If you enable the Abstract PHY mode, the simulation will go faster.

Are you using the msim_setup.tcl script from this directory: <your example design folder>/sim/ed_sim/mentor?

If so than you can run the do file that shared to you to simulate the design.

Thanks,

Adzim

Hi sir ,

Thankyou for the reply,

If I do enable Abstract PHY,mem_* signals will not get anything means ,Abstract PHY enables only PHY not Controller! correct?

I Tried with Abstract PHY enable option too, but i didn't get calib_success!

Basically how much time Will take to complete the calibration?

Thanks for run.do file ,but i didn't see any change! still all the signals have default values except pll_clk,usr_clk !

I don't know what the issue is? am not getting output values?

Hi Venkatesh,

I think the time for finishing calibration should be around 30 minutes or more but it's depends on the device that has been used.

Is there any transaction in the log?

I think you need to let the design run -all and finishes the simulation.

It's will give you the result at the end.

hello sir,

if possible ,could you please share example design and simulation wave form snapshots in modelsim?

Can you share the example design sim scripts and model sim snapshots?

if you are free please Call me +91 8919938367 (india GMT+5:30 ( 9:00 am -6:00 pm)!

Hi Venkatesh,

I'm not able to share the example design for simulation because the size is exceed the limit.

So I would like you to do these:

1. Create new EMIF IP in Parameter Editor.
2. Generate example design for EMIF IP in the Parameter Editor.
3. Go to this path: <example design project directory>/sim/ed_sim/mentor
4. Simulate the msim_setup.tcl with Modelsim.

I can share the EMIF IP setting that I've used to so you can generate the example design with the IP.

The waveform and simulation log also included.

Thanks,

Adzim

Hi sir,

If we enable abstract phy option, how can we test this on custom board? Bcz in ABSTRACT PHY mode only PHY enabled not Hard controller?correct?
