    We present an approach to accelerate the validation speed of behavioral VHDL system specifications through the use of hardware emulation. The method allows source level debugging of behavioral, algorithmic VHDL in a way similar to source level debugging known from software programming languages. We can set breakpoints in the source code and evaluate the contents of variables by reading the registe... View full abstract»

    The teaching of digital design requires a design platform which presents a coherent design methodology to the students. Yet we found ourselves with different tools and hardware subsystems, each having its own idea about what digital design was about. Here we record our effort to forge a single design platform for beginning designers from three separate software subsystems and two hardware subsyste... View full abstract»

    GRAPE-II (Graphical Rapid Prototyping Environment-II) is a hardware-software codesign environment for the real-time functional emulation of synchronous DSP systems. It allows one to specify the application's data dependency graph in a target-machine-independent way. After specifying the heterogeneous target machine's architecture, it estimates the resources needed by each application subtask. Base... View full abstract»

    The need of hardware emulators for logic simulation is becoming a widely accepted requirement, especially as the hardware complexity continues to increase and the design time to decrease. However, raw speed is not the only requirement for a hardware emulator. This paper discusses some of the requirements that designers are demanding from hardware emulation. The main aspect focused on is the applic... View full abstract»

    A low-cost hybrid simulator for VLSI circuits has been under development at IIT Delhi. The simulator uses a Reconfigurable System (RS) consisting of a limited number of FPGAs for hardware emulation and blends the ideas of hardware emulation with conventional software simulation. A crucial preparatory step is to partition a given circuit into as few parts as possible. The parts are then downloaded ... View full abstract»

    The extended partitioning problem is the joint problem of mapping nodes in a precedence graph to hardware or software, and within each mapping, selecting an appropriate implementation for each node. The end-goal is to minimize the hardware area, subject to architectural and performance constraints. This is an NP-complete problem; we present an efficient heuristic called MIBS to solve it. The MIBS ... View full abstract»

    Prototyping has been used to develop electronic systems for a long time. In this work a new prototyping approach, that we named VHDL Virtual Prototyping, is introduced. The new approach introduces VHDL models as the hardware part of the system prototype. The software components of the system are then executed and debugged on top of the hardware models of the system.
