Model Link

VMEBus

VisualSim’s VMEBus library enables Architects and SystemEngineers to predict the response time for requests across a dedicated VME or a Multi-Bus system. This bus is based on the IEEE-1014 standard and has various parameters to match the operation of vendor products

Standards Supported

  • VMEbus IEEE-1014 (40MB/s)
  • VME64 (80 MB/s)
  • VME64x (160 MB/s)
  • VME320 (320 MB/s)

Features

  • The VisualSim library has VME nodes, VME arbiters, bridges and device module templates.
  • Supports all standard speeds up to 320 MB/s and width formats up to 64-bit.
  • VME Arbiter supports Round-Robin, First Come-First Served, and fixed priority schemes.
  • Supports all standard speeds up to 320 MB/s and width formats up to 64-bit.  VME Arbiter supports Round-Robin, First Come-First Served, and fixed priority schemes.
  • Supports block transfer mode with a single address cycle, followed by multiple data cycles.

Working and Usage

  • Used along with the statistical traffic generator and other hardware libraries to assemble a full system.
  • Used to conduct load testing and determine the number of devices that can be supported.

Reports and Analysis

  • Utilization of Bandwidth
  • Can be extended with VisualSim Power Manager to determine the instant and average power consumption of the system.
  • Number of Inputs and Outputs per second and Transaction Counter.
  • Buffer at each device
  • Number of Inputs and Outputs per second and Transaction Counter.
