Abstract: A circuit analysis tool is provided, enabled with software instructions, for minimizing circuit crosstalk. The instructions provide a first circuit connected to an output mode, having a last gate with a plurality of inputs and an output. The instructions calculate a first circuit victim net delay range (timing window) having a minimum delay (Vmin) and a maximum delay (Vmax). A second circuit is provided having an output connected to the output node to supply an aggressor net delay range (A1) having a minimum delay (A1min) and a maximum delay (A1max). The aggressor net delay range at least partially overlaps the victim net delay range. Without increasing the value of Vmax (critical path timing), the first circuit victim net delay range is shrunk, thereby minimizing crosstalk between the first and second circuits without an increase in first circuit maximum signal delay.
