approach to modelling complex digital systems by using electronic design automation software 1 1955 tlm is used primarily in the design and verification of complex systems on chip socs and other electronic systems where traditional register transfer level rtl modeling would be too slow or resource intensive for system level analysis tlm language tlml is a hardware description language usually written in c and based on systemc library 1 tlmls are used for modelling where details of communication among modules are separated from the details of the implementation of functional units or of the communication architecture it s used for modelling of systems that involve complex data communication mechanisms 1 1955 the modeling approach focuses on the transactions or transfers of data between functional blocks rather than the detailed implementation of those blocks or their interconnections 2 this abstraction enables faster simulation speeds often orders of magnitude faster than rtl while maintaining sufficient accuracy for system level design decisions software development and architectural exploration 3 components such as buses or fifos are modeled as channels and are presented to modules using systemc interface classes transaction requests take place by calling interface functions of these channel models which encapsulate low level details of the information exchange at the transaction level the emphasis is more on the functionality of the data transfers what data are transferred to and from what locations and less on their actual implementation that is on the actual protocol used for data transfer this approach makes it easier for the system level designer to experiment for example with different bus architectures all supporting a common abstract interface without having to recode models that interact with any of the buses provided these models interact with the bus through the common interface 4 tlm is typically implemented using systemc a c based modeling language and library developed specifically for system level design 5 the open systemc initiative osci now part of accellera has developed standardized tlm libraries that provide common interfaces and methodologies for transaction level communication however the application of transaction level modeling is not specific to the systemc language and can be used with other languages the concept of tlm first appears in the system level language and modeling domain 6 the methodology has become essential in modern electronic design automation flows particularly for creating virtual platforms that enable early software development and system validation before hardware implementation is complete 7 tlm models serve as executable specifications that bridge the gap between high level system requirements and detailed hardware implementations tlms 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 1 1955 1957 background and history edit early development 1990s 2000s edit transaction level modeling emerged in the late 1990s and early 2000s as a direct response to the increasing complexity of system on chip designs and the limitations of traditional register transfer level rtl modeling for system level verification and software development 8 the semiconductor industry was experiencing a widening disparity between design complexity and designer productivity 9 the foundational concepts of tlm were developed simultaneously by several research groups and companies cadence design systems introduced early transaction level concepts in their specc language in the mid 1990s 10 while synopsys developed similar concepts in their systemc methodology starting in 1999 11 in 2000 thorsten grötker r d manager at synopsys was preparing a presentation on the communication mechanism in what was to become the systemc 2 0 standard and referred to it as transaction based modeling gilles baillieu then a corporate application engineer at synopsys insisted that the new term had to contain level as in register transfer level or behavioral level the fact that tlm does not denote a single level of abstraction but rather a modeling technique didn t make him change his mind it had to be level in order to make it stick so it became tlm citation needed systemc and osci formation edit the development of systemc proved crucial to tlm s adoption systemc was initially developed by synopsys in 1999 as a c based system level modeling language 12 in 2000 the open systemc initiative osci was formed as an independent consortium to develop and promote systemc as an open standard 13 founding members included synopsys cadence design systems coware and several major semiconductor companies including arm holdings infineon technologies and stmicroelectronics 14 the organization developed the osci simulator for open use and distribution since those early days systemc has been adopted as the language of choice for high level synthesis connecting the design modeling and virtual prototype application domains with the functional verification and automated path gate level implementation this offers project teams the ability to produce one model for multiple purposes at the 2010 dvcon event osci produced a specification of the first synthesizable subset of systemc for industry standardization tlm 1 0 standardization 2005 edit the first standardized tlm methodology known as tlm 1 0 was released by osci in 2005 15 tlm 1 0 introduced fundamental concepts including basic transaction interfaces for communication fifo and signal based communication channels simple request response transaction protocols basic timing annotations the tlm 1 0 standard was primarily focused on functional modeling and provided limited support for detailed timing analysis 16 tlm 2 0 evolution and ieee standardization 2008 2011 edit tlm 2 0 released in 2008 represented a major advancement in transaction level modeling methodology 17 the new standard introduced several key innovations generic payloads for standardized transaction representation multiple timing models untimed loosely timed approximately timed standardized socket interfaces for interoperability enhanced debugging and analysis capabilities 18 tlm 2 0 was subsequently incorporated into the ieee 1666 2011 standard for systemc providing official recognition and broader industry acceptance 2 industry adoption and commercial tools edit by the mid 2000s major electronic design automation companies began incorporating tlm support into their commercial tools mentor graphics now siemens eda introduced tlm support in their modelsim simulator in 2004 19 followed by cadence design systems with their incisive platform in 2005 20 virtual platform companies such as coware acquired by synopsys in 2010 21 vast systems acquired by synopsys in 2007 and vast systems technology contributed significantly to tlm s commercial adoption by providing high performance virtual platforms based on tlm methodology 22 modern developments 2010s present edit the 2010s saw tlm become standard practice in the semiconductor industry particularly for arm based soc design arm holdings released comprehensive tlm models of their processor architectures including arm cortex a and arm cortex m series processors 23 the rise of artificial intelligence and machine learning accelerators in the late 2010s created new demands for tlm modeling leading to specialized libraries and methodologies for modeling neural processing units and other ai hardware 24 in 2020 osci merged with accellera consolidating systemc and tlm development under a single organization and ensuring continued evolution of the standards 25 key concepts edit this section is empty you can help by adding to it june
