Atom E3950: need pin delay info file for routing DDR4 signals and the IBIS model for simulation

Hi, 

Our product used the atom E3950 processor. We are now doing the PCB routing of the DDR circuit. We couldn't find the pin delay info file, which is needed to be input into Cadence PCB designer. We will also need to do simulation for signal integrity purpose after the layout is done. So, we will need the IBIS model file for the DDR controller of the E3950. Our simulation software is Hyperlynx. Could you help provide the pin delay info file and DDR4 related IBIS model.

 

Thanks,

 

G. F.

I had already got a Developer Zone Premier Account by following the Intel customer support's instructions yesterday. I think that's the new name for the RDC privileged account.  Please provide the reqested info file and IBIS models.

 

Thanks

Hi, Jaime,

I got your email, and downloaded the IBIS file. Do you have a link for the trace length calculator of E3950? I did find the pin/package delay info in the IBIS model.

 

Thanks

I think I found the package delay info. Because I am searching for the solution for LPDDR4, I didn't found the TLC sheet for LPDDR4 memory. However, there are TLC sheets for LPDDR3 (562062) and DDR3L(570342). Both of them contains the package length for each ball. So, I think I can use these info for LPDDR4, Is that correct?

 

Thanks,

 

G. Feng
