Build time and keep time __FPGA

often composed of combinational logic and sequential logic, so it is very important to establish a clear concept for establishing time and keeping time in order to ensure that data can be treated stably at the interface of these logic. The following questions are considered in the concept of establishing time and keeping time.

Write your own C # framework (11) from scratch-create a solution

in three or two sentences. You can use the video to understand it, but you have no experience and don't know how to do it. So after careful consideration, I feel that, if the implemented code is sent out at one time, too much content is not convenient for everyone to understand some details, or write the code development methods in sequence according to the code implementation steps, features are not implemented at one time. When you need to use related functions, You Can refactor the class or

logic. To ensure that the data at these logic interfaces can be processed stably, therefore, it is very important to establish a clear concept of time and time. The following are some questions about the concept of building time and holding time. Figure 2 a basic model in synchronous design Figure 2 shows a basic model for a unified synchronization design using a clock. In the figure, TCO is the data output delay of the trigger, tdelay is the combination logic delay, tsetup is the trigge
