PCB entry options are usually determined by the version and vendor of the design software. However, entry options for Cadence 17.4 PCB design software may include the following:
1. OrCAD PCB Designer: OrCAD is a full-fledged PCB design tool from Cadence that can be used to create and edit electronic circuit schematics and PCB layouts. Allegro PCB Designer: Allegro is an advanced PCB design tool for complex multi-layer PCB designs, including high-speed circuits and high-density layouts. Allegro PSpice: Allegro PSpice is a tool for integrating analog circuits and mixed-signal simulation into PCB design. It allows designers to validate and optimize circuit designs through simulation analysis.
4. Allegro SI: Allegro SI can help designers perform high-speed signal integrity analysis to ensure that the design has good power consumption and anti-interference capability under various conditions.
Please note that the above options are not the full entry options for Cadence 17.4 PCB software, and specific options may vary by version and software vendor. It is recommended to consult the official Cadence website or software vendor for the latest entry options.
In the process of using Cadence PCB design software, the following two main entrances can be selected for design:
1. Allegro PCB Designer: This is one of the most commonly used and main entrances, providing comprehensive PCB design and layout capabilities. It is suitable for complex multi-layer board design projects, enabling high-speed signal transmission and RF design, as well as simulation of key electrical\/physical characteristics. 2. OrCAD PCB Designer: This is a more simplified and easy-to-use entry level design environment for PCB design projects of moderate complexity. It provides basic PCB design and layout functions, as well as some simple Electrical rule check (ERC) and PCB Routing Specification (DRC) functions.
According to the requirements of the project and the complexity of the design, a suitable entrance can be selected for design. If the project requires more advanced and complex design features, it is recommended to choose Allegro PCB Designer. If the project is relatively simple, or as a beginner, you can choose OrCAD PCB Designer.
