MoC - Model of Computation

A model of computation (MoC) is a set of rules defining the behavior and interaction between SystemC AMS primitive modules. SystemC AMS defines the following models of computation: timed data flow (TDF), linear signal flow (LSF) and electrical linear networks (ELN).

TDF - Timed Data Flow

ELN - Electrical Linear Networks

History

SystemC AMS study group was founded in 2002 to develop and maintain analog and mixed-signal extensions to SystemC, and to initiate an OSCI (Open SystemC initiative) SystemC-AMS working group. The study group has made initial investigations and specified and implemented a SystemC extension to demonstrate feasibility of the approach. In 2006, a SystemC AMS working group has been funded which continued the work of the study group inside OSCI, and now goes on to work on SystemC AMS within the Accellera Systems Initiative, resulting in the AMS 1.0 standard in 2010. After the release of the Accellera SystemC AMS 2.0 standard in 2013, the standard was transferred to the IEEE Standards Association in 2014 for further industry adoption and maintenance. The SystemC AMS standard was released April 6, 2016 as IEEE Std 1666.1-2016. COSEDA Technologies provides with COSIDE the first commercially available design environment based on SystemC AMS standard.
