Re: frequency?????

hi eeeraghu, i have clocks with create clock statements in the .sdc, so which is the source clock?
 

Re: frequency?????

Usually the clock going for most part of the design decides the frequency of operation of that design.
 

Re: frequency?????

There will be one functional clock in ur design which is used by most of your design. It may be the fastest clock (not all times). If u still have more then one clock in functional mode u have to ask the front end designer which is the master clock.
 

Re: frequency?????

you should check how many clocks there are in your design.
