The present technology provides intercloud connectivity as a service by discovering components of the organization's deployment in various sites, irrespective of the cloud provider, such that two sites can merely be selected along with a few standard options, and the controller can handle the complexity of instantiating a tunnel between the cloud sites automatically. Further, the controller can monitor the health of one or more tunnels between the cloud sites to automatically scale bandwidth up or down.

VLAN tagging in a virtual environment is described, including configuring a set of VLAN tagging parameters for each virtual network device to be used by the virtual network device to correctly perform VLAN tagging of frames in response to configuration changes with respect to the virtual network device. A first example of a configuration change with respect to the virtual network device comprises the virtual network device being transitioned from being attached to a virtual switch tagging (VST) port group to being attached to a virtual guest tagging (VGT) port group. A second example of a configuration change with respect to the virtual network device comprises the virtual network device being migrated from a first host to a second host.

This application discloses an electronic design automation tool configured to identify combinational loops in a word-level netlist, and then modify the word-level netlist based on the presence of the combinational loops. The electronic design automation tool can analyze the word-level netlist to identify a portion of the word-level netlist having at least one characteristic associated with a combinational loop, translate the identified portion of the word-level netlist into a bit-level circuit representation, and utilize the bit-level circuit representation to determine whether the identified portion of the word-level netlist implements the combinational loop. The electronic design automation tool can modify the word-level netlist by replacing the identified combination loop in the word-level netlist with a description of a different circuit, such as a loop buffer, or annotate the presence of the identified combinational loop in the word-level netlist.
