Impedance/Length Matching Tracks in PCB Layout | 29 July, 2015

Dear All, Kindly guide me which criteria should follow to do length and impedance matching in PCB layout? Right now I have a design with different type of flip flops, Do I have to length match of data pins of Flip Flops or just rout them as normal signals? In addition to my above query at which frequency range do we need to length match in layout?

Thanks

When it becomes critical. ie impedance influences the design. Pulling a figure out of the air lets say 100 Mhz. If this is a first time board with TTL or 74HC series IC's you are not in that camp.
