Path Type Definition: 

Pad to Pad (tPD) -                        Reports pad to pad paths that start 
                                          at input pads and end at output pads. 
                                          Paths are not traced through 
                                          registers. 

Clock Pad to Output Pad (tCO) -           Reports paths that start at input 
                                          pads trace through clock inputs of 
                                          registers and end at output pads. 
                                          Paths are not traced through PRE/CLR 
                                          inputs of registers. 

Setup to Clock at Pad (tSU) -             Reports external setup time of data 
                                          to clock at pad. Data path starts at 
                                          an input pad and end at register D/T 
                                          input. Clock path starts at input pad 
                                          and ends at the register clock input. 
                                          Paths are not traced through 
                                          registers. 

Clock to Setup (tCYC) -                   Register to register cycle time. 
                                          Include source register tCO and 
                                          destination register tSU.
