Does your code take some time to be executed? Are you limited by a certain time speed and frequency due to the hardware you have? Then let me tell you that taking care of what you write in the code can solve your problem. Writing the right syntax can greatly minimize total time period of your design so that you can keep up with the speed of clock frequency of the hardware. I can review your code and syntax to make sure that you are satisfying all conditions that will lower time spent by design. Do you care about total time taken by your design to get the output? I'll make sure that your VHDL code takes less time in execution through the revision of the required syntax that ensures this process.
