When a design requires specific minimum spacing between net classes, these clearance classes can easily be created and assigned in CR-8000 Design Gateway.
CR-8000 Design Force can help you verify your design before you send it out to manufacture. Before running any signal integrity analysis in Design Force, you must assign device models to the pins in your components using the Constraint Browser.
Do you still use Post-it Notes? Invented in 1979, this simple, yet incredibly powerful, communication mechanism is still commonly found in engineering and design departments. Despite modern electronic communication, many companies still struggle to provide a replacement for their ease-of-use and versatility.
As Zuken technology partners, we are often asked about how best to set PCB constraints for double-data-rate (DDR) memory, and how to route to those constraints. This question arose recently when we were asked to create a common style of DDR3 design for training, and we tried mining the web for detailed information on PCB constraints. There had to be something out there, we thought.
