The connector pane of the emulation VI does not match the ports on the HDL Input Node (in number, order, direction, or data type).

To correct this error, right-click the node and select Properties to open the HDL Interface Node Properties dialog box and select a different emulation VI, change the connector pane of the currently selected emulation VI to match the configuration of the node, change the configuration of the node to match the currently selected emulation VI, or disable emulation for this node.
