INTRODUCTION In a VLSI design, it is often necessary to distribute a signal to several destinations under a required timing constraint at each destination. Furthermore, in practice, there may also be a limitation on the load that can be driven by the source signal. Fanout

A buffer is usually an interposed element which keeps the signal source from being affected by the load attributes but delivers the same or nearly the same voltage and current it sees at its own input. A driver, in contrast, often boosts the current source/sink ... smart card entryWebA Verilog HDL synthesis attribute that prevents Analysis & Synthesis from minimizing or removing a particular register.
