Icc floating pin
Webb4 maj 2013 · Re: Understanding a floating input pin on an IC. Firstly, a floating Input is really only "dangerous" if the environment is noisy AND it is tied to an IRQ or similar (in most cases). If it isn't tied to internal hardware / IRQs, then it can't do much "damage". It's just NOT good "practice" to leave Inputs floating. It is not that simple. WebbFloat pin Stop pin Don't touch sub-tree Don't buffer net Don't size net. Non-stop pin Non-stop pins trace through the endpoints that are normally considered as endpoints of the clock tree. Example: The clock pin of sequential …

WebbICC command: check_design: Checks for multi driven nets, floating nets/pins, empty modules. Pins mismatch, cells or instances without I/O pins/ports etc. SDC Checks: 1. If any unconstrained paths exist in the design then PNR tool will not optimize that path, so these checks are used to report unconstrained paths 2.
