Dear Yash,

 

I implemented a 32-bit adder by targeting a Kintex-7 FPGA by making use of the fast carry logic inherent in the FPGA. a31 to a0, and b31 to b0 are the inputs, and s32 to s0 are the sum outputs. I have attached the Verilog code and the post-place and route static timing report. May I know how to determine the minimum clock period from this report? BTW, does the clock to destination pad delay given in the second table refers to the combinational path delays for the different sum outputs? I would greatly appreciate your early reply.

 

Thanks in advance,

Bala

In this report it is mentioned that you have not used any timing constraint file in your project. first you have to have a  UCF (user constraint file) and try to implement your design again, by then the ISE will give you timing report and timing slack and the maximum frequency of your design.
