PCB Layout CAD : Reading Net Information

Transferring to PCBs (Net Reading) and Importing Netlists

In Quadcept, when designing a schematic, Component Information and Connection Information (Netlists) can be transferred automatically from the schematic to a PCB.
When designing a schematic using another company's CAD, Component Information and Connection Information (Netlists) can be read by importing the Netlist.

Reading Nets
Schematic Design Method

When a schematic is created using Quadcept

Component Information and Connection Information (Netlists) can be read automatically by using Transfer to PCB.
It is necessary to assign footprints to schematics before transferring.

When a schematic is created using other CAD
(Import Netlist)

Component Information and Connection Information (Netlists) can be read by executing Import Netlist for the PCB design drawing.
 


When a schematic is created using Quadcept
Component Information and Connection Information (Netlists) can be read automatically by using Transfer to PCB.
The following will explain how to use Transfer to PCB.
(1) Open the schematic that you want to transfer.
(2) Select [Project]
=> [Transfer to PCB].

=> The transfer destination PCB sheet screen will be created automatically.
(3) Components (footprints) assigned on the schematic will be placed on the drawing, and are connected using the Rats Net based on Netlist Information.

If an error is detected while transferring, the Netlist cannot be read correctly and an error will be displayed.
The Error Description will be shown at the bottom of the screen. After making corrections, execute "Transfer to PCB" again.

 


When a schematic is created using other CAD
(1) Select [File]
=> [Create New]
=> [PCB Project].
=> A new project will be registered in the Project Window, and the PCB sheet will open.
(2)

Select [Project]
=> From [Import Netlist], select a Netlist Format.

Here, [Telesis] is selected.

* When online, by selecting Connect to NET CHANGER, it is possible to import formats from various CAD makers.
 

(3)

Select a Netlist exported from another CAD, and then click "OK".

(4) Configure each setting and then click "OK".
(5)

Components (footprints) will be placed automatically, and the Rats Net will also be connected.

It can be read even after components have been placed and routing has been done.
If there is a difference with the Connection Information between the design drawing and Netlist, Annotation will be performed, and the differences can be confirmed as a list.

Import Netlist Screen

The following will explain the Import Netlist screen.

Component Information
Item Description

Place or Change the Components

Executes new placement and replacement of components and footprints.
In the middle of designing, differences between the PCB drawing and Netlist are detected, and Annotation is performed.

Reference Object

Selects either "Component" or "Footprint".
Specify the object name that is the standard recorded in the Netlist.

During Import Netlist, it is determined based on the match between the Object Name specified as the Reference Object and the Name recorded in the Netlist.

All of the Components

Operates by targeting all components (footprints) being read in Quadcept.

Specifies the Directory (Include Subdirectory)

Operates by targeting all components (footprints) in the specified Directory (including sub directories).

Delete the Component which does not exist in Netlist

When this checked, components that do not exist in the Netlist are deleted from the PCB drawing.

Net Information
Item Description

Delete the Unnecessary Net Objects (Route/Via/Jumper/Test Land)

When this is checked, unnecessary Net object for Import Netlist (Routes/Vias/Jumpers/Test Lands) are automatically deleted.
