WebWhen using a two FF synchronizer, the delay between the two Flip flops must be small to let enough time to metastability to reslove. And that's why we use the set_max_delay ( … WebMar 18, 2016 · FF1_METASTABILITY_FFS is the first flip-flop (the meta stable one) and FF2 is the second flip-flop. A generic 2-FF synchronizer implementation can be found in our PoC-Library as PoC.misc.sync.Bits, as well as two vendor optimized implementations for Xilinx and Altera.

WebDesigners can use special metastable hardened flops for increasing the MTBF. For example, in Figure 4, a synchronizer flop is used following the signal DB. So, instead of the metastable signal DB being used in the function downstream as in Figure 3, the stable signal DB2 is used in the logic downstream. Figure 4: Two flip-flop synchronizer solution WebNov 3, 2024 · Among those locations, I have a set of 2-flip-flop synchronizers for clock-domain crossing purposes to pass signals to slower clock domain. Since most of the resets in my design are driven as synchronous resets, every time I run timing validation the tool shows it failing at the reset stage.

WebMy source of confusion is that I do not synthesize two cascaded flip-flops when I write my code like this: Case 1: reg sync_0; always @(posedge CLK) sync_0 <= switch_input; reg sync_1; always @(posedge CLK) sync_1 <= sync_0; ... You can test what I've said but adding more and more flops to your synchronizer if you wish. WebSynchronizers are used when transferring signals between clock domains. One simple synchronizer design involves simply delaying the input signal (data0) from a different clock domain using multiple edge sensitive flip-flops which are locally clocked (clock0)
