Where can I find fmax?

Hello everyone! 

 

After compiling a new design with multiple kernels, I got the following in my <kernel_name>.log file: 

 

The compiler had to sacrifice circuit frequency (fmax) to achieve initiation interval of one. 

Speed-limiting critical path is shown below. To increase fmax, 

simplify the code on the critical path to do fewer computations. 

 

So it's clear that this particular kernel is forcing the system to run slower, but where can I see the fmax of my design? I ran grep on all the files and didn't see a value for fmax.  

 

Cheers!

Found it. After compiling completely (not intermediate), the info is in:
