Verilog-VHDL Simulation Interoperability

A Verilog-VHDL translating method directed by simulation semantics is presented. Based on the analysis and comparison, three steps are taken to implement the translation. Through semantic analyzing and syntax tree reconstructing before translation, the main part of Verilog is supported. According to the level in the design hierarchy, the modules are translated in down-top order, and that results in a correct VHDL declaration-reference order. The translation rules of assignment statements and delay/timing constructs are also explained in detail. This method has been successfully implemented in the translator developed by the authors. The correctness has been validated by many examples.

Quanta-A platform for rapid control and monitoring of heterogeneous rbots

Rapid prototyping,real-time control and monitoring of various events in robots are crucial requirements for research in the fields of modular and swarm robotics.A large quantities of resources(time,man power,infrastructure,etc.)are often invested in programming,interfacing the sensors,debugging the response to algorithms during prototyping and operational phases of a robot development cycle.The cost of developing an optimal infrastructure to efficiently address such control and monitoring requirements increases significantly in the presence of mobile robots.Though numerous solutions have been developed for minimizing the resources spent on hardware prototyping and algorithm validation in both static and mobile scenarios,it can be observed that researchers have either chosen methodologies that conflict with the power and infrastructure constraints of the research field or generated constrained solutions whose applications are restricted to the field itself.This paper develops a solution for addressing the challenges in controlling heterogeneous mobile robots.A platform named Quanta-a cost effective,energy efficient and high-speed wireless infrastructure is prototyped as a part of the research in the field of modular robotics.Quanta is capable of controlling and monitoring various events in/using a robot with the help of a light-weight communication protocol independent of the robot hardware architecture(s).

Modeling and Simulation of Cooperative Exploration Strategies in Unknown Environments

Cooperative spatial exploration in initially unknown surroundings is a common embodied task in various applications and requires satisfactory coordination among the agents.Unlike many other research questions,there is a lack of simulation platforms for the cooperative exploration problem to perform and statistically evaluate different methods before they are deployed in practical scenarios.To this end,this paper designs a simulation framework to run different models,which features efficient event scheduling and data sharing.On top of such a framework,we propose and implement two different cooperative exploration strategies,i.e.,the synchronous and asynchronous ones.While the coordination in the former approach is conducted after gathering the perceptive information from all agents in each round,the latter enables an ad-hoc coordination.Accordingly,they exploit different principles for assigning target points for the agents.Extensive experiments on different types of environments and settings not only validate the scheduling efficiency of our simulation engine,but also demonstrate the respective advantages of the two strategies on different metrics.
