Saber 2016.03 Release Highlights


Mixed Signal Simulator

Speed & Convergence

Automation &

Customization

Quality and Usability Advanced Analyses

Modeling and

Characterization

Functional Safety

Saber Focus Areas

Proprietary and Confidential

for 2016


Mixed Signal Simulator Speed & Convergence

• SaberHDL Hierarchical Matrix simulator

support for designs with VHDL-AMS (and

MAST) models improves speed and

convergence.

• Builds upon other recent speed and

convergence helpers

–KLU for VHDL-AMS designs (2015.03)

• Important: Standard VHDL-AMS does not

include MAST simulation control features like

Element Template, so some designs will

always work better with MAST models.

Faster simulation for designs with VHDL-AMS or VHDL-AMS and MAST models



Mixed Signal Simulator Speed & Convergence

1. Use hold-nodes to help

convergence of designs without DC

operating points

2. Use hold-nodes to reduce

simulation time by jumpstarting into

steady state

Initialize multi-stable systems using hold nodes for SaberHDL


Set rotor speed (in rad/s) at time = 8 sec


Automation & CustomizationReminder: SaberRD Experiment Analyzer

1) Open\Build SaberRD Schematic

2) Open Experiment Editor & Create new

Experiment

3) Set-up measures, axes for plotting, or pass/fail criteria for

tabular output

4) Simulate single or iterative experiments

5) Analyze results and export to Excel


Automation & CustomizationExperiment Analyzer Export/Import for Verification Test Reuse


Export/Import Experiment to a design variant

2

Experiment Analyzer flags inconsistencies.

3

New design variant is inconsistent with the experiment.

Generate Experiment to test design performance

Automation & CustomizationAdd AIM Scripts to Experiments for Maximum Automation Flexibility


AIM command for graph export.Native EA Graph

Append replace plots (Coming later in 2016)User-defined results display for failed measurements (Coming later in 2016)


Automation & Customization

• Improved AIM programming interface offers

better automation and customization of

SaberRD design environment

• You can download a new migration guide

from SolveNet.

• Guide provides explanations of differences,

walkthroughs, and examples for each main

topic.

Quality and UsabilityEnhanced SaberRD Design Environment for more Efficient Schematic Capture and Site Libraries


• Copy & paste design schematics and symbols among multiple instances of

SaberRD

• Searchable parts from user and site libraries


Advanced AnalysisSaberRD support for familiar stability and network analysis


Linear system analysis (including pole-zero) in SaberRD for stability and other small

signal verification

Modeling and CharacterizationRevamped IGBT modeling tool improves accuracy and makes data sheet matching easier

• Better modeling of gate charge characteristics and turn-

on delays

• Better match transient characteristics

• Better tail current model improves waveforms under soft

switching and reverse blocking conditions

• Expanded library of characterized

components

• Improved usability capturing

curves from datasheets

• Built in tutorials


Modeling and CharacterizationSaber Debug Commands to Test Model Performance

Latent model problems

can affect simulation

convergence and

accuracy.

Saber debug commands

help you find model

problems by testing for

simulation anomalies.

SaberHDL NOW

supports SDB!


SaberRD Functional Safety Add-onReminder: Saber Functional Safety


Functional Safety

Vary design parameters within fault loops

to optimize a design for fault response.

Improved productivity selecting, simulating, analyzing faults

Nearest neighbor short on converter output.

• Automates fault selection and

configuration without direct schematic

interaction

• Import/Export of fault sets

Vary component values inside fault loop.

Copy & paste of

faults for rapid fault

set creation.


SaberES Designer


SaberES Designer

Highlights:

– Intuitive user interface provides simple,

seamless integration between functional,

wiring, and harness development phases

–Flow-driven instead of feature-driven flow

guides you through vehicle electrical system

design process

–Wiring design verification using voltage drop

simulation and Saber Experiment Analyzer

reduces system cost and physical prototyping

time, and eliminates expensive field failures,

Next Generation Design Tool for Electrical Systems and Harnesses
