Capture Driven Pre-Route AnalysisIn Capture schematic electrical constraints and topologies can be:

– Analyzed– Assigned– Edited– Stored

This includes the support of xnets

Work Flow:1. Capture: SI Model Association2. Capture: Assign DC Nets3. Capture: Topology Extraction (.TOP)4. OrCAD SI: Analyze / Edit Topology5. OrCAD SI: Update Capture with topology incl. constraints6. Capture: Netlist to PCB Editor7. PCB Editor: Topology and Constraints enter Constraint Manager

Save

• Only Pages and Library components modified by user are marked for save

• Design, Schematic and Pages that require Save are marked (*)

• Better visibility, when unwanted changes happened on pages

Enhanced Productivity

SaveAs• Project SaveAs enables user controlled save of

associated files also along with the project at the new location while maintaining their references. Available Options– Copy DSN to Project Folder– Rename DSN to match Project– Copy All Referred Files Present

Within Project Folder– Copy All Referred Files Present Out

of Project Folder

• Save associated files include:– referred projects, designs, libraries, simulation

profiles, output files etc.

Enhanced Productivity

21

CIS Reference Designator• No more manual corrections in CIS-BOM for Refdes• Synchronized handling of Refdes in CIS BOM with

Capture database. CIS now supports all Refdes formats like:– U2N– C1_R– C12-1– C0001– R7-TOP– MP_2V5_REF– TP3V3_0

• Consistent Refdes for multi-packages– MP_2V5_REF shows as MP_2V5_REF – and not MP_2V5_REFA

Enhanced Productivity

22

Find & Replace

• Find Enhancements– Search for Property = specific Value– Use Regular expressions for matching Values– Examples

• PCB Footprint=dip2*• Part Reference=(C|R)[2-9] finds all parts with

references starting with R or C followed by any number between 2 and 9

• Global Find and Replace support available for Offpage Connectors

Enhanced Productivity

23

Cache Update

• Replace Multiple Cache Parts in one operation• All options of Replace Cache now work on Update Cache

Enhanced Productivity

(C) FlowCAD Confidential

24

Read only open

• There will be no upref executed on read only designs• Upref will be executed, if you save

• Allows users to review a schematic without upref– Opens fast– Gives Warning when changes were performed

(C) FlowCAD Confidential

25

NetGroup Enhancements

• NetGroup membership visible on schematic and schematic print

• Assign NetGroups through Alias

(C) FlowCAD Confidential

26

Shapes for Hierarchical Block

• Use Edit Part forhierarchcal blocks

• Shapes can be storedin the library

• Looks alike as block diagram

(C) FlowCAD Confidential

27

Auto Reference

• Provides Auto-Reference assignment for Entire Design– Previous releases were

limited to Schematic level only

• Schematic Level auto-reference for Pspice

• Reference & Part reference are always in sync

(C) FlowCAD Confidential

28

Preserve User Assigned Reference

• User Modification to Reference is detected and marked by Capture

• Annotation Process has new options to manage Reference Assignments

(C) FlowCAD Confidential

29

CIS – Link Database Part

• Part manager allows Link for External Design parts

• Link Part at Instance or Occurrence? Systems decides based on user inputs and design data

(C) FlowCAD Confidential

30

Export/Import XML

• Define Environment Variable to generate TCL– CAPTURE_WRITE_TCL_ONXMLIMPORT=1

• XML Import/Export Commands– XMATIC_DSN2XML – Design to XML– XMATIC_XML2DSN - XML to Design – Generates TCL– XMATIC_OLB2XML – Library to XML– XMATIC_XML2OLB – XML to Library – Generates TCL

• Schema (xsd) available in <install>\tools\capture\tclscripts\capdb– dsn.xsd– olb.xsd

(C) FlowCAD Confidential

31

Enhanced Configurability…• Add your own TCL Customized

DRC Applications

• Sample DRC provided– Hanging Wires– Device Pin Mismatch– Overlapping Wires– Reference Prefix mismatch– Port-Pin Mismatch– Shorted Discrete Part

(C) FlowCAD Confidential

32

Waive DRCs

• Waive Selected DRC

• DRC waived are hidden from future DRC runs

• User can remove waived DRCs

(C) FlowCAD Confidential

33

Customize your Tooltips

• TCL callback allows user to customize tooltips for different object types

• Hybrid Application Framework allows Graphical Tooltips!!

(C) FlowCAD Confidential

34

OrCAD Design Database Upgraded

• Database Transaction Support– Enables consistency over the

network operations– Prevents corruption of library and

design data

• Database Compaction– Deletion of objects reduce file size

immediately

• TCL Enabled - Support for file storage within Capture DSN file

(C) FlowCAD Confidential

35

Configuring CIS…

• CIS supports columns larger than 255 characters• Customize Part Placement Checks

– For example - Configure to disable placement of an EOL part– For example - Configure to warn a user if part procurement has

long lead time

• Highlight CIS rows for designers– For example – BLUE recommended part, RED not

recommended

45

Encrypting Tcl Scripts

• To encrypt Tcl scripts in Capture, you should use the orcad::encrypt command from the Capture Command window.

• Syntax:orcad::encrypt <path to Tcl script> [output_file]

Example:

orcad::encrypt myFirstApp.tcl

Encrypted TCL Applications can be tied to licensing

optional
