OrCAD Capture

• DRC check added to ensure pin numbers on parts are correct

• Checks for missing and invalid pin numbers

• Helps prevents incorrect netlists being sent to PCB

• DRC may be customized – <installation>\tools\capture\tcls

cripts\capDRC\capInvalidPinNumber.tcl

Physical DRC Check – Invalid Pin Numbers

• Digital Electronics and Data Convertors chapters added to ‘Learning with PSpice’

• Instructional / introductory material on – Logic Gates – Latches – Flip-flops – Shift Registers

• PSpice Mixed-signal simulator chapters – Data converters – Analog-to-Digital (ADC) – Digital-to-Analog (DAC)

Learning with PSpice

OrCAD PSpice

• 5 levels of speed upgrades – Default speed level is 3 – Speed level 0 should be set for

compatibility with previous releases

• Removed multi-core usage limit and default multi-thread usage – Previous releases used 50% of the

available threads up to four cores

• Speed levels allows faster switching of devices and shows substantial improvement – In test cases with switches, more

than a 5x performance improvement has been measured at level 3

Speed Upgrades

Significant upgrade in PSpice performance

• Previous releases required a high ITL4 values when using Switches circuits to achieve convergence – At low ITL4 values, convergence errors

were observed – At high ITL4 values, performance and

mathematic errors were frequently observed

• With QIR7 improvements, it is recommended to use lower values of ITL4 to achieve convergence and performance – Note: using SPEED_LEVEL=0 will

require high ITL4 values to converge

Convergence Improvements

Designs with Switches converge at

lower ITL4 values

• App to measure Steady State loss of energy in a magnetic core for power supplies

Hysteresis Core Loss Calculator

• HTML report generated for Analog Transient simulation – Average, RMS, and Peak

values of Current, Voltage and Power can be reported

• User customizable – Tcl source available in

installation hierarchy – <installation>\tools\pspice\tclsc

ripts\orPspReport

• .TCLPOSTRUN command can be used to configure auto-generation of HTML reports

New Simulation Report Capability

• Advanced Analysis Parts are now available through PSpice Searcher – Use search string ‘A/A Enabled’

to find all A/A parts

• Searcher symbol viewer updated

PSpice Search – Advanced Analysis Parts

Miscellaneous

Miscellaneous

• Object Distribution feature has been enhanced to force equal spaced distribution − Setup available in Extended Settings

to revert to previous behavior

• Fix conditions for PSpice returning incorrect results for certain circuits − Re-simulation − Biaspoint PseudoTran

• Increased number of Libraries supported in OrCAD Capture Configuration − Earlier limit was 199

• BOM_IGNORE is now supported for hierarchical designs

• Fix crash for Advanced Analysis with 64-bit DAT files
