Transaction-level models are used for high-level synthesis of register-transfer level (RTL) models for a lower-level modelling and implementation of system components. RTL is usually represented by a hardware description language source code (e.g. VHDL , SystemC , Verilog ).

TLM establishes a connection between producer and consumer components through which transactions are sent.

Transaction-level Modeling (TLM) standard interfaces for SystemC provides an essential framework needed for model exchange within companies and across the IP supply chain for architecture analysis, software development and performance analysis, and hardware verification.

In the introduction, we describe the motivation for proposing a Transaction Level Modeling standard, focusing on the main use cases and the increase in productivity such a standard will bring. In Section 2, we describe the core tlm proposal in detail.

Product development teams using virtual prototyping require a comprehensive set of transaction-level models (TLMs) that serve as the building blocks of virtual prototypes. Synopsys offers the broadest set of models, covering performance optimized processor models and peripheral.

Jul 14, 2011 · For this article, I propose to create a SystemC TLM-2.0 un-timed model for the PL011 UART, starting from the same ARM specification I used in my previous experiment. Modelling the Registers. The first step is to capture the …

Feb 27, 2006 · Transaction level models (TLMs) can help with design, integration and verification issues associated with large, complex systems. TLMs allow designers to model hardware at a higher level of abstraction, helping to smooth the integration process by providing fast simulation and simplifying the debugging process during integration.

Transaction-level modeling (TLM) is a technique for describing a system by using function calls that define a set of transactions over a set of channels. TLM descriptions can be more abstract, and therefore simulate more quickly than the register-transfer level (RTL) descriptions more traditionally used as a starting point for IC implementations.

Since its release, TLM has become the industry standard for creating interoperable transaction-level models. It provides a synergistic and comprehensive solution that supports loosely-timed and approximately-timed transaction-level modeling.

Feb 3, 2011 · TLM basically abstracts the signal-level details of a communication protocol into a function call. This function call specifies the attributes of a payload -- the command, address, data, enables, etc.
