Hi,
following question:
I have a signal in an 48MHz clock domain, it is high for exactly one clock cycle. Now I want to pass it to an 90MHz clock domain where the synchronized signal should also be high for one 90MHz clock cycle. Is the following approach reasonable?
signal l_valid_48 : std_logic; -- high for one 48MHz clock cycle signal l_valid_h1 : std_logic; signal l_valid_h2 : std_logic; signal l_valid_h3 : std_logic; signal l_valid_90 : std_logic; -- should be high for one 90MHz clock cycle
process(Reset, Clk_90) begin if Reset='1' then l_valid_h1
