Honored Contributornon-application pin Model for Cyclone II
Is there something like a physical model, describing the behaviuor of such pins like Status, nConfig, MSEL and these ? I am setting up a system to load and automatically reload FPGAs with new i...

Honored ContributorHello,
You can find information about Power UP, Reset, Configuration and initialization in a PDF named "configuring altera fpgas" . About timing , you may look at device handbook (chapter "configuring ...."). Timing depends on device, options (fast programming, ...) and environment (power state, CRC checking...) Other way, I am testing an home made "auto reconfiguration" in cyclone II by wiring a i/o pin to nconfig pin of the fpga itself trough a 1kohm resistor. Is there constraints with AS Programmation headers (pin 5) ? or other bad thing i have not seen ? ++
