false if there is no timing relationship from `fromPort` to `toPort`. false if there is no timing relationship from `fromPort` to `toPort`.
### IdString getPortClock(const CellInfo \*cell, IdString port) const ### TimingPortClass getPortTimingClass(const CellInfo *cell, IdString port, IdString &clockPort) const
Returns the clock input port for the specified output port. Return the _timing port class_ of a port. This can be a register or combinational input or output; clock input or
output; general startpoint or endpoint; or a port ignored for timing purposes. For register ports, clockPort is set
### bool isClockPort(const CellInfo \*cell, IdString port) const to the associated clock port.
Returns true if the specified port is a clock input.
