Some synchronous elements, in particular shift registers and dedicated RAM blocks, can be created by describing their behavior in Verilog or VHDL (by inference): The synthesizer usually creates a shift register
In the Verilog code of Example 1a and the VHDL code of Example 1b, a flip-flop is used to capture data and then its output is passed through a follower flip-flop. The first stage of this design is reset with a synchronous reset. The second stage is a follower flip-flop and is not...

The effect of the constraints on the designs and the way they are handled by the synchronous CAD tools are analyzed and reported in this work. The automation of the generation of asynchronous design templates and also the constraint generation is an important problem. Algorithms for automation of...
It needs to be 'SYNCHRONIZER_IDENTIFICATION FORCED' as a virtual clock makes it synchronous (to quartus). This is the reason for the SDC behaviour above. Now, I have the same 1 Billion year MTBF analysis in both cases.The answer is in this page,https://www.intel.com/content...
1. Asynchronous Reset, Synchronous Release Asynchronous Reset, Synchronous Release Several registers are chained together. Those registers have async reset pin connected to external reset input. WhenARST_INasserted, all registers andARST_OUTgoes to 1 immediately. AfterARST_INde-assert, it takes several...
