Do file commands ModelSim?

DO files are essentially a very basic scripting language for ModelSim. In essence, DO files contain a list of commands that are run in the ModelSim command prompt. In previous labs, you may have used some of these commands to force inputs to a particular value or run the simulation.

What are do files?

A DO file is a web-based Java program run by a web server that supports Java, such as Tomcat or IBM WebSphere. It is typically mapped to the Struts controller, which processes the file. DO files are used for generating dynamic webpages. Some webinar programs may generate DO files that are formatted as .

How do you force a clock in System Verilog?

How do you create a clock code?

What is a clock enable?

Clock enables allow processors and other functional blocks to be clocked at different speeds. They control the frequency relationship between a high rate clock and a lower rate synchronous clock that can be applied to a slower functional block. Clock enables must be used for generating continuous clock pulses.
