Define setup time

In this post, I will cover the differences in use and function between setup vs. I will give real life examples from national newspapers and magazines, and you will be able to test your knowledge at the end with a quiz. What does setup mean?

Setup one word is a noun and is defined as the way in which something is constituted, arranged, or planned. Another meaning of the one-word setup is a scheme or trick intended to incriminate or deceive someone. Need even more definitions? Merriam-Webster's Words of the Week - Jan.

Similarly, if hold check is violated, data intended to be captured at the next edge will get captured at the same edge. It may lead to metastability failure in the design as explained in our post ' metastability '. On the other hand, a design with hold violation cannot be run properly. So, if you fabricate a design with an accidental hold violation, you will have to simply throw away the chip unless the hold path is half cycle as explained here.

A design with half cycle hold violations only can still be used at lower frequencies. The setup slack can be defined as the difference between the L. S and R. In other words, it is the margin that is available such that the timing path meets setup check. On the other hand, a negative slack means that the paths violates setup timing check by the amount of setup slack. To get the path met, either data delay should be decreased or clock period should be increased. Mitigating setup violation : Thus, we can meet the setup requirement, if violating, by.

Decreasing the propagation delay of the combinational cloud. Reducing the setup time requirement of capturing flop. Increasing the skew between capture and launch clocks. Increasing the clock period. Tackling hold time violation : Similarly, the equation for hold timing check is as below:. The parameter that represents if there is a hold timing violation is hold slack. The real value is knowing what to do with your cycle time information.

Takt time and cycle time are often discussed together — and often confused for one another. Unlike cycle time, takt time is the time that a single product must be produced in order to make your customer goals on time. Therefore, for your company to provide on-time delivery, your system must be set up so that your cycle time is less than your takt time. Knowing your cycle times allows for the proper setup of your processes.

In a manufacturing setting, it allows for the proper setup of the production floor. It is important for understanding how many machines, tools, and personnel are needed. If you find out that your cycle time is currently larger than your takt time, you can make modifications to the line.

Adding the right personnel, machinery, and additional tools can decrease the cycle time, eventually getting it under your takt time. Cycle time is also used to help identify if there are improvements that can be made to the system. Even if cycle time is less than takt time, changes in the environment may increase the cycle time. Regularly monitoring your cycle times will allow you to identify unexpected cycle time increased due to previously unpredicted changes.

Perhaps a shortage of material causes delays, or a machine has unexpected downtime, causing an increase in cycle time. It is key to monitor cycle times to verify that customer demand will be met, as well as to identify possible cost-savings initiatives.

In many cases, a process that takes less time may be a less expensive process to manage. Should I use the cycle times present in my companies, or should I try to manually track the times?

This is a challenging issue, as few computer systems do a great job of tracking certain times. Overall, most computer data systems do a great job of telling you the overall cycle time for a product but do a poor job of verifying a cycle time for a specific part of the process. This is because many companies have poor tracking regarding when the product leaves one part of the process and enters another.
