Cadence® Allegro® Design Entry HDL streamlines the high-speed design process by merging schematic design with PCB design. It combines schematic design entry capabilities with extensive simulation and board layout solutions, and serves as the "productivity hub" for all CAE-required tasks associated with system design flow. Within Allegro PCB Design XL series, Allegro Design Entry HDL XL easily integrates with Allegro Constraint Manager to assist in the high-speed design process. Integration with Cadence Incisive® simulators further enables digital simulation (Verilog®, VHDL) and Allegro AMS Simulator/PSpice® for analog simulation.

Key benefits


Assigns and manages high-speed design rules for nets such as differential signals using the embedded Allegro Constraint Manager
Integrates with Allegro AMS Simulator, Incisive simulators, and Allegro PCB SI for simulation and signal analysis for PCB or FPGA design flows
Allows synchronization of logical and physical designs using visual design difference tools
Ensures integrity of design among multiple users through team-based design entry support with systematic version control
Enables a customizable user interface by offering modifiable menus and toolbars to accommodate company, group, or individual needs, as well as SKILL for developing new commands
