An integrated software tool for system noise management is described. A system noise management suite for an assembly includes an integrated circuit design to be coupled to a circuit board design. The system includes three modules and a user interface. The first module is configured to determine at least one type of bounce voltage for the assembly. The second module is configured to identify decoupling capacitances for the assembly to reduce power distribution system noise. The third module is configured to estimate jitter caused by the integrated circuit design. The user interface is coupled to the first module, the second module, and the third module for input of information for the first module, the second module, and the third module.
