This also affects the reference clock of the IOPLL for the lvds core. At the moment, I will update the design and check if the error still occurs. Once I get first results, I will give you an update. Thanks. Michael Translate 0 Kudos Copy link Reply All fo...
4, there is a fundamental constraint (the no-go theorem) on δ-continuous models for single systems: there are no δ-continuous ψ-epistemic models with δ≥ 1 − (d − 1)/d reproducing the measurement statistics of quantum states in a Hilbert space of dimension d. Mathematically, the...
These SOCs, with multi-billion transistors, serve as the core of iPhones and iPads. We focus on Analog/Mixed-Signal (AMS) circuits, including SerDes for data communication, PLLs for clock generation, and sensors for measuring all sorts of physical quantities. Analog Layout Engineers are essenti...

I believe I need to add a negative phase shift to reduce the clock delay on the data path. I've tried this but then I get failures elsewhere. Do I need to add multi-cycle path constraint on both inputs and outputs? Any help is much appreciated! Translate Tags...
