Altium Designer also has a set of features for advanced schematic capture. It allows you to simplify working with multi-sheet and multi-channel designs through hierarchical conversion, which displays the schematic on single sheets in an organized manner.

[2] Layout and Routing

Manual routing in Proteus does not need to be started from the ratsnest lines. You can lay traces in any manner, and the system will handle removal of ratsnest lines. Even while manual routing, the system will follow the mouse movement and avoid or move around obstacles intelligently.

You can edit routes and re-route if needed, or even delete older sections of the rack. The thickness and layer of any tracking can also be modified later through commands. The program uses active rule checks while routing as well, to ensure that the design is valid and standard-compliant.

Proteus offers shape-based autorouting. The router works on a cost-reduction algorithm which favours solutions to conflicts in favour of reducing cost and maximising completion.

Users can have a higher level of control if required, through the option of writing custom code to drive the routing process by dynamically entering commands to the router. Proteus provides a great level of flexibility by allowing routing specific areas or net classes and the option to set the direction and length for fanout routing.

With Altium, you get an advanced manual and automatic routing experience. The manual routing includes interactive routing options such as hug and push, push and shove, obstacle avoidance, diff pair routing and more.

The autorouter offers a higher level of control over the process by allowing you to set and define routing parameters. The rule checking systems are also active during the routing and can pre-emptively indicate rule violations so that they can be corrected.

[3] Design Verification and Rule Checking

Proteus actively works to check rules and verify the design as you place each single track and indicates any violations. The constraints for the board are fully customizable and the rules can be defined specifically for certain regions such as a layer or a custom selected area.

The bottom panel of the workspace shows real-time connectivity and the DRC status. You can easily access any reports by clicking on the respective component in the panel.

To provide even stricter quality control, the system performs a pre-production check before manufacturing and works as a quality assurance check. This also checks the power plane geometry, power and signal integrity and runs specific tests to find any other mistakes.

Altium Designer also has a real-time rule checking system. While you route the board, the system can predict and indicate rule violations and suggest alternative routes. It also features a constraint manager, which lets you selectively apply constraints for projects.

[4] User Interface and Functionality  

The workspace you design the PCB in, is the user interface, with all the tools and options, panels and navigation bars.

Proteus is a professional platform for experienced designers, and has been in the market for over 25 years now. In that time, it has improved by leaps and bounds. Proteus is now available in various versions to suit different user bases.
