Embedded System Design Challenges

companies such as Parametric
Technologies (PTC) or Dassault
Systemes helped to manage the

Sw paradigm
In the SW paradigm, the system
design enables the use of the
processor abstraction
(computer architecture) to gain
access to massive amounts of
functionality from the software
ecosystem. The processor
abstraction allows the
developers of software to
maintain and leverage their
investment across a large
number of implementation
platforms.
This critical property of the
processor abstraction allows for
deep investments and
associated returns. Further, a
combination of commercial and
open-source ecosystems can
provide enormous capability and
at the same time allow for the
crowd sourcing of innovation
from a wide variety of sources. It
is not unusual to find many
vertical embedded applications
where the SW provides the
majority of the value. Finally, the
SW abstraction has its own
ecosystem of tools such as
compilers, operating systems,

loaders, device drivers, and board support packages.
The acceleration and magnitude of value provided
by the SW paradigm is at a scale that in many cases,
embedded system designers must start with the
selection of the SW ecosystem and build the rest of
the system around that decision. In the past,
embedded system designers often " snapshotted " the
software stack, but with the tradeoff of missing
ongoing innovation. Today, increasingly embedded
systems are building processes for field updates of
the software stack. A seminal moment in this
paradigm was Tesla's decision to allow for over-theair
updates.
From a system design point of view, the SW
paradigm introduces significant complexity because
one must manage two independent ecosystems that
operate at a different cadence. The process of
mapping design intent to underlying components is
difficult due to this lack of coordination and the
