Meeting Agenda

• Continue to Review Interfaces from May 14, 2015 and May 28, 2015
• Reviewed SV Interfaces
• Procedures in ModPorts may not be necessary as if an "disallowed" subprogram is called it will result in driving interface signals that are inputs.
• Ports on interfaces - required to allow clk to be part of multiple interfaces
• Virtual Interfaces - Are actually a pointer to an interface. They are good for BFMs that have multiple threads to select among.
• Reviewed Interface Concepts
• Do we need a mechanism to select portions of an interface - SV does this
