Today’s most advanced PCB technologies including high-density and high-speed, multi-board designs, have unique requirements. CR-8000 2018 has delivered new solutions to address these requirements.
The focus of CR-8000 2018 is on enabling front-loading of design constraints and specifications to the design creation process, coupled with placement and routing capabilities for physical layout. This will increase efficiency and ensure quality through collaboration across the PCB design chain.
Front-loading of design intent from Design Gateway to Design Force has been achieved by adding an enhanced, unified constraint browser for both applications. This enables hardware engineers to assign topology templates, modify differential signals and assign clearance classes to individual signals. Using a rule stack editor during the circuit design phase, hardware engineers can now load design rules that include differential pair routing and routing width stacks directly from the design rule library into their schematic. Here they can modify and assign selected rules for improved cross talk and differential pair control. Finally, an enhanced component browser enables component variants to be managed in the schematic, and assigned in a user-friendly table.
Manual routing is supported by a new auto complete & route function that layout designers can use to complete manually routed traces in an automated way. Designers also have the option to look for paths on different layers while automatically inserting vias.
A new bus routing function allows layout designers to sketch paths for multiple nets to be routed over dense areas. An added benefit is the routing of individual signals to the correct signal length as per the hardware engineer’s front loaded constraints, to meet timing skew and budgets. If modifications to fully placed and routed boards are required, an automatic re-route function allows connected component pins to remain connected with a simple reroute operation during the move process.
