OrCAD Capture schematic entry tool for circuit diagrams is one of the world's most widely used software for entering and documenting electrical circuits. It is outstanding how simple and intuitive the design intentions are captured. OrCAD Capture uses flat or hierarchical circuit diagrams. Via the navigation window the different pages of the circuit diagram can be selected and thematically managed.
Using the PartBrowser, circuit diagram symbols are selected with the aid of filters from the library and placed in the circuit diagram. The electrical connections (networks) between the associated component pins can be quickly established. In the case of hierarchically structured designs, the same electrical networks are interconnected via cross-porting ports or defined as global networks.
Variants are defined in the schema editor and later output as variants with different parts lists for each variant. In OrCAD Capture can be created with a PCB by means of different mounting devices with a varied range of functions. If programmed components are used in the circuit, pin assignments and signals from FPGAs from different manufacturers can be read. It also supports a design methodology that integrates the vendor tools of the FPGA manufacturers into the place and route of programmable blocks. Changes in the logic can be easily imported into the circuit diagram. OrCAD Capture is also the module for switching inputs from PSpice network lists to simulate analog and mixed-signal circuits.
For designs incorporating programmable devices (such as FPGAs), an Engineering Change Order (ECO) flow is supported, which synchronizes various work steps in the FPGA tool, the circuit diagram, and the PCB editor by forward and backward annotation. Using the CIS option, circuit diagram symbols and data sheets from online databases can be placed directly in the circuit diagram. The CIS option also allows you to transfer component information from a company-owned database.
OrCAD Capture is a powerful schematic entry tool for capturing the design intent of an electronic circuits. It has many special features which support an efficient and easy methodology.
Cross probing between the schematic and the PCB layout makes it easy to place analog circuits from the schematic into the PCB and keep analog circuits close to each other. Cross probing and highlighting from PCB to Schematic helps to understand a finished layout for debugging or bring up and test.
In hierarchical designs the description of a net name might be different. When you import a lower level block, you want to keep signal names unchanged. Whereas in higher levels you might use signal names which corespond with the system architecture. It is important to know, what physical net name is used in the layout as well.
For documentation a smart or intelligent PDF can be generated from the schematic. This PDF contains net names, properties and constraints which can be searched in Adobe Acrobat Reader.
When two versions of a schematic are loaded in OrCAD Capture, the differences between these two designs can be compared. As a result you will see if components are moved or connections are altered.
Schematics from Altium® and Eagle® can be imported into OrCAD Capture. Symbols can be used and stored in the library. Complete schematics can be imported.
The parts distributor Arrow® offers more than 10.000 refence designs in OrCAD Capture format. After registration these designs are free to the designer community for download directly into OrCAD Capture. This is a good starting point for new functional blocks.
OrCAD Capture is part of Cadence flows certified to use with ASIL A through ASIL D in automotive design projects. Functional safety documentation kits cover OrCAD Capture for analog, digital, and mixed-signal schematic entry and verification all the way to implementation and signoff in a PCB flow.
OrCAD Capture can be customized with TCL-Scripting Language. TCL is a standard programming language in Electronic Design Automation (EDA). There are many TCL commands available and the scripts can be used to perform specific tasks or checks in the schematic.
Create a signal integrity tolopology and derive designrules from it to drive a schematic driven PCB layout flow.
Mit einer kostenlosen App kann in der Leiterplatten-Entwurfssoftware OrCAD Capture in wenigen Minuten die Test-Coverage der Schaltung angezeigt werden. Die App wurde von XJTAG, einem Anbieter von Boundary-Scan-Hardware und Software-Tools, entwickelt. Mit diesen frühzeitigen Informationen über die Testbarkeit wird ein Design For Test deutlich vereinfacht und so die Anzahl von nachträglichen Änderungen deutlich verringert.
