Ip Delivery For Fpgas Using Applets And Jhdl

Decent Essays

Paper Summary The paper, “IP Delivery for FPGAs Using Applets and JHDL”, describes the use of Java applets in order to provide IP (Intellectual Property) based FPGA delivery and evaluation. As IP-based FPGA approach has significant advantages such as it improves the productivity/quality, and reduce design time. FPGA IP uses Java applets that allow designers to create, evaluate, test and obtain circuits, and that too has to be done within a web browser. Several other approaches have been introduced, which are similar to JHDL. Those can be described as follows;  Web-CAD: It uses client-server architecture and transfers the simulation events across the network  Java CAD: This is similar to Web-CAD. It has applets which are described in Java and uses RMI (Remote Method Invocation) over the internet for simulating and evaluating the circuits.  JBits: This tool does not use the internet to deliver IP cores and delivers pre-placed IP core. It is easily incorporated with online Java applets. In Java-based applets, here “JHDL” is used as a design environment. It is developed at BYU used for creating high-performance FPGA. JHDL libraries provide the components and wires that are used to create the instance. The programming language used here is Java and for simulation and compilation, Java Virtual Machine (JVM) platform is needed. Variety of design tools it supported, such as  Schematic Viewer, allows the designer to quickly view the structure and hierarchy of a circuit. 
