AM6442: Pin-delay

James Jang

Part Number: AM6442
Other Parts Discussed in Thread: AM62L, AM62D-Q1

Tool/software:

Does AM6442x provide pin-delay for each pin so can implement into the layout constrain manager ?

Presumably looking for the especially DDR, RGMII, etc signals. (Also GPIO pins since some GPIO pins are mapped for RGMII interface)

Hi James,

Kindly refer to this E2E thread: AM6422: AM6422 package pin delay

I believe you will find the answer in the Verified Answer there.

Thanks,

Stan

Hello James,

We are now supporting pin delay for DDRSS.

Refer below FAQ

The pin delay is part of the DDR design guide.

For the AM64x the DDR design guide updated is in plans.
