Also, you can create new packages on the drawing if required. Proteus supports 2D drafting features. This software features a direct import tool for PADS ASCII layout format. Therefore, this allows you to bring in footprints from popular tools like Ultra-Librarian.

Manual routing

With the manual routing feature, you don’t need to begin from the ratsnest lines. Also, tracking can easily be places in any way you want. Proteus will help you get rid of ratsnest lines as the connections become complete. When placing tracks, the route will follow the mouse anywhere possible and will move around obstacles.

You can delete any section of a track or reroute when you are editing routes. Also, there are commands that help you change the layer of a section of tracking. If there are thick tracks between obstacles like IC pads, there will be automatic necking in the route. Therefore, this will help you maintain the design rules.  Also, you can lay down curved tracks by simply pressing the CONTROL key and using your mouse to mark the route.

Templates and technology data

Proteus has a PCB layout module that comprises a detailed scheme for design re-use. Also, this scheme is in the form of technology data and board templates. As a user, you can design several templates that represent common projects. Also, you can start new layouts from the template. This will help you preload all the configured data.  

A template file is a basic layout together with a technology data set. Also, this data features grids, design rules, and more. You can directly apply this data to other layouts.

Power planes

This software includes ultimate power plane support. Also, there is a user placeable polygonal region in which there is a creation of inner boundaries around existing pads and tracking. The boundaries will be recomputed to ensure design rule clearances once you change the tracking and pads. Also, Proteus includes support for thermal relief. So, you can decide whether to fill or hatch every polygon.

All computation on Proteus is according to grid-less shape geometry. Also, this computation occurs in the background. This will prevent any interference in the placement of manual board for computationally intensive layouts.  Placing several power planes for each layer is one of the advanced features set by Proteus. Also, you will need the Proteus PCB design Level 2 to achieve this.

Verification

Proteus ensures it checks every track and warns if there is any violation of design rules. Also, you can set rules by strategy or by layer to customize the board constraints. You can even design rules that control behavior between strategies. There is an indication of the board’s design rule and connectivity on the status bar at Proteus’ bottom.

3D visualization

Proteus has a 3D visualization tool that helps you extrude a PCB layout.  3D visualization is one of the more advanced features provided by Proteus. Also, this feature enables you to view what the board would look like in the real world. This feature is very useful during PCB layout. Navigation is very intuitive and is controlled by mouse.

Also, the user can define a “height pane” that matches the board chassis. This will display as a box around the board, enabling a visual check for any protrusions. Also, Proteus features 3D footprints and support for designing custom 3D footprints. You can export files in these formats from most commercial MCAD packages and a wide range of free internet resource.

Stitching and shielding

Via stitching helps to tie larger copper traces together on various layers. Therefore, this helps to maintain short return paths and minimize noise on the circuit board. Also, planes can be automatically stitched through a simple context menu command. Therefore, this gives you control over via style.

You can include a picket fence or via shield around the planes’ border in the same way. Therefore, this will form a single row of vias around the zones’ perimeter. Also, this can help to prevent EMI with other equipment. This technique is ideal for high-speed routes to isolate signals on the board operating at various frequencies.
