Synchronous Resets? Asynchronous Resets ... - Sunburst …
www.sunburst-design.comblock the reset from reaching the flip-flop. This is only a simulation issue, not a hardware issue, but remember, one of the prime objectives of a reset is to put the ASIC into a known state for simulation. Second, the reset could be a “late arriving signal” relative to the clock period, due to the high fanout of the reset tree.
Asynchronous & Synchronous Reset Design Techniques - …
www.sunburst-design.comEach Verilog procedural block or VHDL process should model only one type of flip-flop. In other words, a designer should not mix resetable flip-flops with follower flip-flops (flops with no resets) in the same procedural block or process[14]. Follower flip-flops are flip-flops that are simple data shift registers.
