Design begining. How to estimate frequency

Design begining.

Hi Friends...

Here in this forum we had been talking a lot about timing, multicycle path etc etc..bla bla bla.....

My doubt is, before we begin any design say 50 MHz, or 60 MHz or any thing, how we will get a rough idea that my design will run in that frequency. If we dont have an idea of rough frequncy of our target will run, its going to be a wilds goose chase, because once our design is coded and its not running...AAHHHHH...
The company will come to ruins.

Plz share your views.

Regards

hmm.... frequency depends on the application..so first u need to fix the application where ur design is sitting ...then u need to check at which frequency u will get the expected results.....
Once u have rough idea of the frequency, check the same with the silicon vendor and their components will run at ur desired frequency (this means u need 2 check the timing of each n every block like comparator, subtractor, flipflop timinings etc.....)
Then u can start designing
