Abstract

Embodiments relate to multi-cycle signal identification for static timing analysis. An aspect includes identifying, in a circuit under test, a multi-cycle signal, the multi-cycle signal having a longer period than a main clock signal of the circuit under test. Another aspect includes mapping a plurality of additional signals of the circuit under test onto the multi-cycle signal, the plurality of additional signals each having a shorter period than the multi-cycle signal. Yet another aspect includes performing static timing analysis of the circuit under test based on the multi-cycle signal.
