Hi,


Yes I have. Can you please try set_multicycle_path as stated in the email? I have sent detailed information in email.


Regards,

Nurina

    Hi,
    In addition to what I sent in email, I want you to see again this picture that happens when I don't define 'multicycle path' :



    Also another question - do the real clock and virtual clock should be in the same async group?
    set_clock_groups -asynchronous -group [get_clocks { main_clk main_clk_virt}]
