The SMV system is a tool for checking nite state systems against speciications in the temporal logic CTL. The input language of SMV is designed to allow the description of nite state systems that range from completely synchronous to completely asynchronous, and from the detailed to the abstract. One can readily specify a system as a synchronous Mealy machine, or as an asychronous network of abs...

| Software/Hardware Engineering (SHE) is a new object-oriented method for the co-speciication and design of complex reactive hard-ware/software systems. SHE incorporates a framework for design activities, and a formal description language called POOSL (Parallel Object-Oriented Speciication Language). Starting from informal object-oriented analysis, SHE produces rigorous system-level behaviour a...

Hardware description languages (hdls) are a notation to describe behavioural and structural aspects of circuit designs. We discuss why it is worthwhile to give a formal semantics for an hdl, and why we have encoded such a semantics in a proof system. We outline the subset of the hardware description language ella 2 which we use, its formal structural operational semantics, and its embedding in ...

The increasing complexity of data-processing systems forced the design methodologies to move to a higher abstraction level (Shin, Gerstlauer, Dömer & Gajski, 2008) than the traditional register-transfer level (RTL). In the 2000s the so-called electronic system level (ESL) paradigm was evolved including the system level description languages, such as SystemC, SystemVerilog and the high-level syn...

We describe work-in-progress which aims at compiling suitably restricted functional programs with lazy lists directly into hardware. This extends previous work on SAFL which demonstrated that functional languages are effective at describing “fire-and-wait-for-result” programs, but for which stream-like I/O was awkward or impossible. Other frameworks (e.g. Lava) have used functional languages as...

We present a short description of the capabilities of the experimental scripting language Open PROMOL. It has been developed aiming: 1) to deliver flexible means for representing wide range modifications of a target program, and 2) to support white-box reuse for well-understood domains, such as hardware design. We describe the syntax and semantics of the basic constructs of the language. We dem...

The ability to carry over models and testbenches from one level of abstraction to another is becoming increasingly important to the design and verification of system designs. This capability delivers the benefits of reuse with a scalable methodology. It therefore enables engineering teams to leverage the particular strengths of different modeling domains. For example, take the behavioral testbe...

We describe a methodology for the formal verification of the correctness, including IEEE-compliance, of register-transfer level models of floating-point hardware designs, and its application to the floating-point units of a series of commercial microprocessors produced by Advanced Micro Devices, Inc. The methodology is based on a mechanical translator from a synthesizable subset of the Verilog ...

The use of Field Programmable Gate Arrays (FPGA) to rapidly produce custom hardware circuits using a completely software-based process is becoming increasingly widespread. Specialized Hardware Description Languages (HDL) are used to describe and develop the required circuits. In this paper, we advocate using an even more general purpose programming language, based on Occam, for the automatic co...

With increasing complexity of modern embedded systems, the availability of highly optimizing compilers becomes more and more important. At the same time, application specific instruction-set processors (ASIPs) are used to fine-tune hardware platforms to the intended application, demanding the availability of retargetable components throughout the whole tool chain. A very promising approach is t...
