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.
