Systems and methods are provided for computing write margins for dual-port memory. A design for a dual-port memory array cell is generated using a circuit design tool. A user modifies the design of the dual-port memory array cell to incorporate two voltage sources. The voltage sources are used to represent differential noise on the memory cell. A write margin calculation tool uses a circuit simulation tool to perform transient simulations of write-during-read operations on the modified dual-port memory array cell. During the transient simulations, the voltage level on the voltages sources is systematically varied. The write margin for the dual-port memory is determined by analyzing the results of the transient simulations for each of the voltage levels used for the voltage sources.
