    Getting setup and hold time violation

    Hi all, I have acheived a frequency of 50 MHz after place and route. But still i am getting setup and hold time violation when i am running the timing simulation for 50 MHz. Anyone has idea why its failing for the frequency that it has acheived after place and route? Thanks & Regards, Srilekha

    regd : dutycycle of clock

    HI u have missed to declare the data type of dc so its taking dc as single bit and assigning the lsb value 1 of (101) and creating a clk of duty cycle 2 ns. i have declared dc as integer and this code will generate a clk of duty cycle 5 ns and a total clock cycle of 10ns. as u expect module...
