Input will be constrain in vlsi
WebSetup Time Constraint • The setup time constraint depends on the maximum delay from register R1 through the combinational logic. • The input to register R2 must be stable at least t setup before the clock edge. T c ≥ t pcq + t pd + t setup t pd ≤ T c – (t pcq + t setup) WebNew concepts of worst-case delay and yield estimation in asynchronous VLSI circuits . × ... which estimate worst case delays at design time and constrain the clock cycle accordingly. Desynchronization is a new paradigm to automate the design of asynchronous circuits from synchronous specifications, thus, permitting widespread adoption of ...
