Honored ContributorIOE and delay chain?
Can i have a silly question here? :confused: May i know what is IOE (I/O Elements)? why delay chain (D1,D2,D3,D4) is always related to IOE? What is the IOE role in the FPGA? Thanks, ...

Honored ContributorYes, you may.
The IOEs (I/O elements) are the circuitry blocks that actually connect to the FPGA I/O pins. They have the I/O drivers (the circuits which let the FPGA interface with TTL, CMOS, LVDS, SSTL, etc external components) and also tend to have some features to improve I/O timing, like dedicated I/O registers and programmable delay chains.
