The LogiCORE™ IP Virtual Input/Output (VIO) core is a customizable core.
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.
Certain AMD technologies may require third-party enablement or activation. Supported features may vary by operating system. Please confirm with system manufacturer for specific features. No technology or product can be completely secure.
