ChipScope PRO Virtual Input/Output (VIO)
Overview
The LogiCORE™ IP ChipScope™ Pro Virtual Input/Output (VIO) core is a customizable core that can both monitor and drive internal FPGA signals in real time. Two different kinds of inputs and two different kinds of outputs are available, both of which are customizable in size to interface with the FPGA design.
Key Features
- Provides virtual LEDs and other status indicators through asynchronous and synchronous input ports
- Has activity detectors on input ports to detect rising and falling transitions between samples
- Provides virtual buttons and other controls through asynchronous and synchronous output ports
- For synchronous outputs, provides ability to define a pulse train, which is a 16-cycle train of ones and zeros that run at design speed
