In principle, there are four options: Accept that the initial value of the register is unknown. Rely on the initial value setting of the FPGA's synchronous element. So the there is no explicit reset. Use an asy

The simulation model of a flip-flop that includes both an asynchronous set and an asynchronous reset in Verilog might not simulate correctly without a little help from the designer. In general, most synchronous designs do not have flop-flops that contain both an asynchronous set and asynchronous ...

Reset signals cause a sequential circuit to fall into some predetermined start state without the intervention of a clock. Their effect is immediate, unconditional and always the same. Practically speaking, this includes all asynchronous reset and set inputs present on many bistables, but none of ...

Algorithms for automation of reset addition to asynchronous circuits and power and/or performance optimizations applied to the circuits using logical effort are explored thus filling an important hole in the automation flow. Constraints representing cyclic asynchronous circuits as directed acyclic graphs ...
This problem arises mainly from the lack of support for asynchronous circuits in the synthesis tools. Asynchronous circuits require redundant logic to function correctly and by default the synthesis tools removes the redundancy. By using setting similar to do not modify, the synthesis tool do not ...
