EXTERNAL PORTS
These are the external ports defined in the MHS file.
Attributes Key The attributes are obtained from the SIGIS and IOB_STATE parameters set on the PORT in the MHS file CLK  indicates Clock ports, (SIGIS = CLK)  INTR  indicates Interrupt ports,(SIGIS = INTR)  RESET  indicates Reset ports, (SIGIS = RST)  BUF or REG  Indicates ports that instantiate or infer IOB primitives, (IOB_STATE = BUF or REG)
