To improve the performance of your FPGA, you have to take the path-delay into account.
My suggestion is as below.
1: Change your synthesize software, as KARNIZHU says, use synplify premier.
2: Insert registers for all ports of A & B modules.
3: Add constraints for clock and critical path, refer to synplify help-doc for constraint-performance curve.
4: If you implement arithmetic operation with codes, replace it with IPcores or add multicyle and falsepath constraints.
5: If possile, do not utilize LogicLock and manually place clock-routing. For beginner, it is so puzzling.
I wish it is helpful for you. |
