Challenges in Electric System Design
• Electronic systems in automotive
growing at 10% per year
• More electronics = Optimization of
wires and physical connections
• More models served by one platform
• Large number of design options to
meet diverse marketing requirements
• Impossible to verify by prototypes,
must have automated simulation
• Need to minimize giveaways from over
engineering

Buildable
Harnesses
• Loose connections
mean that merge
takes weeks!
• Changes are difficult to
keep consistent and
don’t get propagated
often leaving electrical
schematics outdated

Harnesses
• No weeks-long merge!
• Changes made in
master data are easily
propagated through

SaberES Designer
Intuitive user interface with seamless
integration between development
phases (Logical, Wiring, Harness)
Interface to 3D MCAD Tools
Automated verification
• Automated Test Environment
• Voltage drop testing- simulation
vs. calculation
• Time-domain simulation,
frequency domain simulation, etc.
are an optional add-on
Platform for Electric System Design & Verification

A main and unique advantage is the concept of a single
design database
Even though portions of the design are in separate schematics/files, they are aware of each other
• For example, you can’t use a resource, such as a connector cavity, which is already consumed elsewhere
Built-in revision control enables global collaboration
Consistency is maintained from the start, not merged or checked at the end; correct-by-construction
