Overview

The LogiCORE™ IP Virtual Input/Output (VIO) core is a customizable core that can both monitor and drive internal FPGA signals in real time. The number and width of the input and output ports are customizable in size to interface with the FPGA design. Because the VIO core is synchronous to the design being monitored and/or driven, all design clock constraints that are applied to your design are also applied to the components inside the VIO core. Run time interaction with this core requires the use of the Vivado® logic analyzer feature.

Key features

  • Provides virtual LEDs and other status indicators through synchronous input ports
  • Includes optional activity detectors on input ports to detect rising and falling transitions between samples
  • Provides virtual buttons and other controls through synchronous output ports
  • Includes custom output initialization that allows you to specify the value of the VIO core outputs immediately following device configuration and start-up.
  • Run time reset of the VIO core to its initial values

Designing FPGA Based Reliable Systems Using Virtex-5 System Monitor

The fast track development and 24x7 operations have put tremendous pressure on the servers, networking systems and communication equipments. It has become necessary that these systems should operate reliably irrespective of the change in external operating environment like the temperature, humidity, and power fluctuations or, on chip conditions like on-chip temperature, internal voltage levels etc. Measuring the reliability of these physical systems is must for every operational unit.

How to maximize FPGA performance

The more that can be done upfront with good coding styles, timing constraints definition, and resource planning, the easier it will be for the downstream tools to achieve timing requirements.
