How to verify timing for Agilex DDR4 Post Layout
Hello,
How do I verify that my layout is meeting timing requirements with Agilex 7 and a Quartus Prime Pro 24.1.0.115.
I am trying to verify that a DDR4 design meets timing requirements post-layout in Hyperlynx. I'm using an Agilex 7 and am not able to find anything in Quartus/EMIF User Guides that provide evidence that I'm able to do this accurately.
It appears that Intel no longer supports designers ability to do this as I'm not seeing evidence of a) Quartus exporting a timing report .v file nor do they b) import board characteristics (i.e skew/propagation delay) in the EMIF IP for timing analysis.
I am a novice at using Quartus so maybe I'm just missing something, any assistance is appreciated!
Hi,
Quartus no longer perform the timing analysis on DDR based on pcb characteristics for Agilex devices.
You should follow the routing guideline and skew matching guidelines from the UG.
