Hi am doing LINT analysis for our design using cadence HAL it generates a warning as

halstruct: *W,FFWASR (../../test.v,620|0): Flip-flop 'a47' does not have any asynchronous set or reset.
a47 <= out47;

We designed the logic using synchronous reset mechanism only.
How can i analyze the above warning ?
Can i ignore it?

Then the warning msg makes sense.

By looking at your RTL code and comparing it with the translated flop after synthesis.

I don't know your design, so can't comment on it.
 


This is why FFWASR is a warning and not an error. It's benign for this design as you know that was not the intention.
