text: Faced with increasing demands on energy efficiency, current electronic systems
operate according to complex power management schemes including more and more
fine-grained voltage frequency scaling and power shutdown scenarios. Consequently,
validation of the power design intent should begin as early as possible at electronic
system-level (ESL) together with first executable system specifications for integrity
tests. However, today's system-level design methodologies usually focus on the
abstraction of digital logic and time, so that typical low-power aspects cannot
be considered so far. In this paper, we present a high-level modeling approach
on top of the SystemC/TLM standard to simulate power distribution and voltage
based implications in a "loosely-timed" functional execution context. The approach
reuses legacy TLM models and prevents the need for detailed lock-step process
synchronization in contrast to existing methods. A case study derived from an
open source low-power design demonstrates the efficiency of our approach in terms
of simulation performance and testability.

text: Today, mobile and embedded real-time systems have to cope with the migration
and allocation of multiple software tasks running on top of a real-time operating
system (RTOS) residing on one or multiple system processors. Abstract RTOS simulations
and timing analysis applies for fast and early estimation to configure it towards
the individual needs of the application and environment. In this context, a high
accuracy of the simulation compared to an instruction set simulation (ISS) is
of key importance. In this paper, we investigate the accuracy of abstract RTOS
simulation and compare it to ISS and the behavior of the physical system. We show
that we can reach an increased accuracy of the simulation when we inject noise
into the time model. Our results indicate that it is sufficient to inject uniformly
distributed random time values to the RTOS real-time clock.

text: We present the syntax and semantics of a past- and future-oriented temporal
extension of the Object Constraint Language (OCL). Our extension supports designers
to express time-bounded properties over a state-oriented UML model of a system
under development. The semantics is formally defined over the system states of
a mathematical object model. Additionally, we present a mapping to Clocked Linear
Temporal Logic (Clocked LTL) formulae, which is the basis for further application
in verification with model checking. We demonstrate the applicability of the approach
by the example of a buffer specification in the context of a production system.

text: We present a rigorous but transparent semantics definition of SystemC that
covers method, thread, and clocked thread behavior as well as their interaction
with the simulation kernel process. The semantics includes watching statements,
signal assignment, and wait statements as they are introduced in SystemC V1.O.
We present our definition in form of distributed Abstract State Machines (ASMs)
rules reflecting the view given in the SystemC User's Manual and the reference
implementation. We mainly see our formal semantics as a concise, unambiguous,
high-level specification for SystemC-based implementations and for standardization.
Additionally, it can be used as a sound basis to investigate SystemC interoperability
with Verilog and VHDL.
