“…In this Electronic System Level (ESL) design context the major advantages of SystemC are the development of hardware and software, the support of different levels of abstraction by Transaction Level Modeling (TLM) [1], the modeling of heterogeneous systems (containing digital, analog and RF) [2], [3], and the IP integration based on standardized TLM protocols [4].…”

Abstract-Design and verification of embedded systems at the Electronic System Level (ESL) is common practice. In particular, Transaction Level Modeling (TLM) is the major reason for the success of ESL design. However, when detailed protocols are modeled at lower levels of TLM, the verification of the communication becomes a critical issue. In this paper, we present an approach for protocol compliance checking of new or detailed protocol implementations. They are checked against user-specified protocol sequences. We also analyze the protocol coverage achieved by the testbench and visualize the results on a protocol sequence graph. Experimental results for a SoC model demonstrate the advantages of our method.

“…Although it resembles existing HDLs and adds more features for digital modelling, it does not support AMS modelling as yet. A study group was established in 2003 [23] following a proposal submitted to the SystemC board of directors to form an Open SystemC Initiative OSCI working group tasked to develop AMS extensions to SystemC, named SystemC-AMS. This is proving to be a difficult task as many associated research issues still remain unresolved.…”

Abstract-This paper presents a new methodology that enables extensions of SystemC to the analogue domain and allows modelling of mixed-signal and mixed energy-domain systems at arbitrary levels of abstraction. The new language constructs support analogue system variables, analogue components and user defined ordinary differential and algebraic equations. Support for digital-analogue interfaces has been provided for smooth integration of digital and analogue parts. Associated issues such as dealing with extremely small and zero time-step sizes have been addressed. A novel implementation of the lock-step mixed-signal synchronisation method to integrate the analogue kernel with the digital one has been proposed. Operation of the extended, mixedsignal simulation platform, named SystemC-A, is demonstrated using a suite of numerically difficult AMS examples including a practical, mixed-signal example of a PLL frequency multiplier with large-signal noise and jitter.

“…Operation of the extended, mixed-signal SystemC simulation platform is demonstrated using practical example of a boost power converter, in which analog behavior tightly interacts with a digital control loop. The results presented here might aid the current efforts to standardize analog extensions for SystemC [8].…”

We describe an efficient implementation of analog and mixedsignal extensions integrated with SystemC 2.0. SEAMS (SystemC Environment with Analog and Mixed-Signal extensions) uses a general-purpose analog solver to handle analog extensions and to provide modelling capabilities for general, mixed-mode systems with digital and non-linear analog behavior. We have extended the SystemC 2.0 kernel to invoke and synchronize our analog solver in each simulation cycle while maintaining compliance with the SystemC simulation cycle semantics. The operation of SEAMS is illustrated with the practical examples of a boost power converter and a 2GHz phase-lock loop frequency multiplier with noise and jitter models. Mixed-signal systems of this kind are known to be difficult to simulate as they exhibit disparate time scales which put most simulators in numerical difficulties. We hope that the practical experience of SEAMS might aid the recent efforts to standardize analog and mixed-signal extensions for SystemC.
