Meaning of Fast/Slow model at IOE Delay at Cyclone 10GX

[phillip]

Hi everyone,

I'm really want to know meaning of Fast/Slow model at Programmable IOE Delay Section.[Intel Cyclone 10 GX Device Datasheet]

I'm using 10CX220YF780E6G Device.

Is Fast/Slow model base on Temperature/Voltage at real environment?

Hello,

Thank you for reaching out to Intel FPGA Community.

The fast model and slow model are subject to PVT (process, voltage, temperature) variations.

Concept of PVT (process, voltage, temperature) variations are too abstract word for me.

Could you provide some example(diagram, graph, chart)?

Hi,

I found this one website from the external resource (out of Intel). Maybe the explanation there will be helpful for you to understand.

Please refer here: Process-Voltage-Temperature(PVT) Variation | vlsi4freshers

Thanks for reply.

May i ask you one more think?

How could i decide one step input delay of IOE in given environment.
